Recently a post on LinkedIn reminded me of an idea I had a few years ago for a motivational book I called “The Power of F”.
What is the power of F, you ask?
Yeah, I am sure you are asking.
My idea was that you could take a set of words that have negative connotation (e.g., “lie”) and make them positive "(“life”) with the simple addition of the letter ‘f’. You know, turn your LIE into a LIFE, go from being LAME to a FLAME, stop being RANK and start being FRANK.
Not the greatest idea I ever had, I admit.
But the idea, as my ideas tend to do, never really left my head.
Something about it, the simplicity of just changing perspective with the addition of one letter, appealed to me. Change, even difficult change, is often the result of a change in perspective or a reframing of something through a new lens.
Don’t get me wrong — I know change can be very difficult. I also know that change can ask a lot of us, sometimes more than we have to give. I struggle with this myself, even at this very moment (looking at you: glass of wine on my desk).
The great F idea got put away, in one of the 782 notebooks I keep around my office.
Then it came back when I read that LinkedIn post. And I shared it in a comment, and it started reverberating in my head again.
I asked myself, is it a good idea at all? How many words would actually qualify to change from positive to negative with the addition of an ‘f’ at all?
Fortunately, we live in the golden infancy of AI, and getting the answer to this question was simple as pie!
Here are some excerpts from my dialog with Claude:
INITIAL PROMPT:
We are going to play a little language game and I need your help. The premise is that the addition of the letter 'f' to many common words takes them from a potentially negative connotation to a positive connotation (e.g., Lie + f + Life). Please generate a list of all the common 3 and 4 letter English words that become other common English words with the addition of the letter 'f' in any position. Show this list with the original word next to the new word. It is ok if some words can become two different words depending on where the 'f' is placed. Ask me any clarifying questions required. Thanks.
A RESPONSE (after some additional prompting):
I'll analyze cases where adding 'f' either maintains a negative connotation or shifts from positive to negative.
Counter-examples where adding 'f' creates/maintains negative meanings:
Three-letter to four-letter transformations:
air → fair (while "fair" can be positive, it can also mean "merely adequate")
end → fend (from conclusion to defend against/ward off)
act → fact (from action/performance to something potentially harsh - "hard facts")
eat → feat (while "feat" is often positive, it carries connotations of difficulty/struggle)
Four-letter to five-letter transformations:
lint → flint (from mundane to hard/harsh)
rail → frail (from path/track to weak/delicate)
ring → fling (from lasting/permanent to brief/casual)
Cases where 'f' placement matters:
ear → fear (hearing → anxiety)
low → flow (while both can be neutral, "low" to "flow" doesn't necessarily improve connotation)
Interesting patterns in these counterexamples:
Position Effect
When 'f' is added at the beginning, it seems more likely to create negative connotations if:
The original word is already strongly positive
The 'f' combines with certain consonant clusters (fl-, fr-)
Semantic Categories
Physical weakness/fragility (frail, faint)
Fear/defense (fear, fend)
Impermanence (fling, fleet)
Context Dependency
Many 'f' words can carry both positive and negative connotations depending on context:
"fair" (just vs. mediocre)
"fine" (excellent vs. barely acceptable)
"fast" (quick/efficient vs. reckless)
This analysis suggests that while 'f' often creates positive transformations, its effect is not universal and can be influenced by:
The original word's meaning
The resulting consonant cluster
The position of the 'f' addition
The broader semantic category of the resulting word
Would you like to explore any of these patterns more deeply?
(I pointed out an error Claude made in one of the responses and had the list regenerated):
'll create a comprehensive, verified list of common words that transform by only adding 'f', organized by both length and connotation shift.
3-Letter to 4-Letter Words:
ace → face (neutral → neutral)
ail → fail (negative → negative)
all → fall (neutral → neutral)
arm → farm (neutral → neutral)
ate → fate (neutral → neutral)
ear → fear (neutral → negative)
ill → fill (negative → positive)
ink → fink (neutral → negative)
lag → flag (negative → neutral)
lap → flap (neutral → neutral)
lat → flat (neutral → neutral)
led → fled (neutral → negative)
lie → life (negative → positive)
old → fold (neutral → neutral)
our → four (neutral → neutral)
4-Letter to 5-Letter Words:
lame → flame (negative → positive)
lash → flash (negative → neutral)
lush → flush (positive → positive)
rank → frank (negative → positive)
lint → flint (neutral → neutral)
rail → frail (neutral → negative)
ring → fling (neutral → neutral)
Notable Positive Connotation Shifts:
ill → fill (unwell → complete)
lie → life (deception → vitality)
lame → flame (inadequate → vibrant)
rank → frank (unpleasant → honest)
Notable Negative Connotation Shifts:
ear → fear (neutral → anxiety)
rail → frail (sturdy → weak)
ink → fink (neutral → informer)
led → fled (guided → escaped)
This revised list has been verified to ensure:
Only 'f' is added with no other letter changes
All words are common to a U.S. high school graduate
No archaic or technical terms
No proper nouns
All transformations are legitimate English words
FINAL PROMPT:
Great, thank you for your help. Did you gain any new insights yourself in this exercise?
RESPONSE:
Yes, I found several interesting insights through this exercise:
Working systematically revealed that the initial perception of 'f' creating predominantly positive transformations wasn't as strong as it first appeared. While there are some clear positive shifts (ill→fill, lie→life), there are nearly as many negative shifts (ear→fear, rail→frail).
The position of the 'f' addition seems significant. Most transformations occur at the beginning of words, creating 'fl-' and 'fr-' consonant clusters. This suggests something fundamental about English word formation and phonological patterns.
The exercise highlighted how context-dependent word connotations can be. Words I initially categorized as clearly positive or negative often revealed more nuanced meanings upon closer examination. For example, "flame" can be positive (passion, brilliance) or negative (destruction) depending on context.
The importance of rigorous verification became clear when you caught the "rash→fresh" error. This reminded me that pattern-matching can sometimes lead to false positives if we're not carefully checking each transformation against the original criteria.
Perhaps most interestingly, this exercise demonstrated how single-letter changes can create dramatic semantic shifts in English, suggesting the efficiency of our linguistic system in creating meaning through minimal changes.
Would you like to explore any of these insights further?
You can make of all this what you will. For me, it continued to support the notion that a single interesting idea does not a whole theory make.
Also, my conversation with Claude didn’t end there…we explored all the other letters in the alphabet and words longer than 5 characters looking for examples of a single letter consistently changing connotation of the word from negative to positive. Short answer is some (many) ideas are best left on the drawing board.
