It's an honest-to-goodness English word and not derived from French, Latin, Greek or anything else, like a lot of the words here. Yes, it looks like it might be from an African language, but it's a squashed form of "in keen bow" meaning "well bent" or "crooked".
We take it for granted now, but I'm sure we all questioned the word at one point in our lives, the shortest word guaranteed to fool any child who is an intuitive spelling pro if they don't already know the word's spelling.
It's just odd that you're supposed to say it like it rhymes with "love".
It's also almost always with other words, so by itself it truly looks suspicious.
I think "once" is spelled strangely. In Spanish it's 11 and pronounced as you would expect.
In English the same string of letters is pronounced wonss. Plus the whole once twice thrice for one time two times three times is odd, though at least consistent but then no fourse or anything it just stops.
I feel like we will change a lot for digital reasons, especially in coming centuries.
lemmatization - in linguistics is the process of grouping together inflected forms of a word so they can be analyzed as a single item, identified by the word's lemma, or dictionary form; (eg. walk [lemma], walks, walked, walking)
Things like inflected forms and parts of speech that can not be coded easily really have no use in the future. Things like how a sentence can be "I am here." but when I must change more than one word to say "He is here." The am/is change is nonsense of no use. It is like a deep inner conflict with no solution; a prejudice or bias.
