In many instances, both "start" and "beginning" can be used as an antonym of "end". But which is better? In particular, which is better for units of time like day, week, or month?
I'm thinking of "better" in terms of etymology and accepted usage. For example, just to make something up: if "start" was of Greek origin and "end" of Latin origin, one could argue that they are not the best pairing.
(What I'm really looking for here are the "acronym antonyms" for things like EOD, EOW, EOM for end of day, week, and month. Which is better: SOD, SOW, SOM, or BOD, BOW, BOM?)
