One thing that drives me nuts about some words (because I’m
the kind of person who’s driven nuts by words) is that a lot of them are
completely meaningless without their prefixes. Take compute for example. There’s
also words like dispute and repute (and even impute and suppute are words,
though not really used), but take away the prefix, and pute is
nothing.
Compute is a late comer, having first showed up in the early seventeenth century,
with computer showing up shortly after (not as the current definition of course :), and both coming two centuries
after computation did.
The words share an origin in the classical Latin computare, to calculate. The com- prefix means with,
but putare has more varied meanings. It generally means think or suppose.
“Think with” makes sense as a computer is a tool for thinking, although it’s
amusing that once upon a time putare meant “to prune”, like you would a tree. Because sure, why not?
Dispute is much older than any of the com- words. It showed
up in the early fourteenth century,
coming from the Old French disputer, dispute or fight over, and
classical Latin disputare, debate. Dis- means separately or apart from here,
so added to suppose or think about, it’s “think separately”, or differently,
than someone else. Wow, that actually makes sense.
Finally, we have repute, which showed up in the late fourteenth century from the Middle French reputer and classical Latin reputare, to consider.
The re- prefix means repeatedly,
making the word “to think repeatedly”, which makes sense since considering
something is thinking about it a lot. And of course, it’s related to
reputation.
TL;DR: Pute means think. Learning achieved.
