I was thinking the other day. Fuck isn’t an unpleasant word. The soft eff-sound stays forward in the mouth, not like finger or finch. The crisp kah-sound at the end could obtain a harshness, but it so rarely does. It’s a brief, multi-faceted, one-syllable word that can range from playful to surprised, angry to erotic.
It gets a bad rap, I guess owing to its connection to sexuality. But maybe it’s a word that just needs further research, and a bit of love.
