v.动词
commence, begin, originate, start这组词都有“开始”的意思。其区别是：
1.commence和start有时可互换,但在作“动身,出发”解或某一活动过程的“开始”解时,只能用start。
2.commence强调缓慢地开始,而start强调从不动到动或停止后再动。
3.start往往强调“开始”这一行动本身,而commence则含有为了某一目的的意味。
4.commence比begin要庄严得多,含有正式开始或开幕的意味,如开始举行典礼、开始审讯案件等。
5.begin是最常用语; commence多用于书面语; start则多用于口语。
6.originate作不及物动词时,表示“源自”“起始”“发起”等意思; 用作及物动词时,表示“创始”“发明”。
begin，start，commence，initiate，inaugurate这些动词均含有“开始”之意。
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。
start在许多场合可与begin通用，但start侧重动作的起点。
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”。
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。
inaugurate指正式而隆重的开始。
