记忆方法
1、plus 是拉丁"更多"——比 multus（多）更一级的比较级，出自 pele"装满"古根：与 fill（装满）、full（满的）一家——装得满满，自然"更多"。
2、加号 "+" 就是它的口头读法；数字后 plus 表"还带个尾巴"：thirty plus 三十出头；名词转义"加分项、优势"——a plus 一大优势。与 minus（减号）成对。
3、拼读直接 /plʌs/；作连词"而且"是美式口语。plus size 加大码，plus 一路都在"多"。

英语词源
- plus (n.)
- 1570s, the oral rendering of the arithmetical sign +, from Latin plus "more, in greater number, more often" (comparative of multus "much"), altered (by influence of minus) from *pleos, from PIE *pele- (1) "to fill" (see poly-).
As a preposition, between two numbers to indicate addition, from 1660s. [Barnhart writes that this sense "did not exist in Latin and probably originated in commercial language of the Middle Ages."] Placed after a whole number to indicate "and a little more," it is attested from 1902. As a conjunction, "and," it is American English colloquial, attested from 1968. As a noun meaning "an advantage" from 1791. Plus fours (1921) were four inches longer in the leg than standard knickerbockers, to produce an overhang, originally a style associated with golfers. The plus sign itself has been well-known since at least late 15c. and is perhaps an abbreviation of Latin et (see et cetera).
