Etymology
Origin of accumulate
First recorded in 1520–30; from Latin accumulātus “heaped up,” past participle of accumulāre “to heap up,” from ac- ac- + cumul(us) “heap” ( see cumulus ( def. )) + -āre, infinitive verb suffix
Explanation
To accumulate means to gather, usually in large quantities. Let's hope your boyfriend is not the type to accumulate girlfriends. The root of accumulate is cumulus which means "mound" or "heap." You might have heard of cumulus clouds, those big fluffy clouds that look like giant piles of whipped cream. Think of these heaping helpings of clouds when you think of accumulate.
