Spelling with double -m- began in French and was established in English by 1500. Related: Commenced; commencing.

inaugurate: 指正式而隆重的开始。
commence: 可与begin换用，但commence系书面正式用词，语气庄重，特指有正式程序或一定仪式，或某种正式行动的“开始”。
start: 在许多场合可与begin通用，但start侧重动作的起点。
initiate: 指创始或发起，侧重某过程的第一步，不考虑结束，强调起始。
begin: 最常用词，含义广泛，其反义词是end，多用于行动、工作等的开始。
