maintain

音標發(fā)音

13世紀中期進入英語，直接源自盎格魯法語的meintenir；最初源自拉丁語的manu tenere：manu (手） + tenere (握著，拿著），意爲用手拿著。

maintain的基本意思是“保持”“繼續(xù)”,指採取某種手段或措施保畱一種有價值的東西,使其獲得保養(yǎng)竝維持良好狀況,有時也指使事情能正常持續(xù)下去,引申可表示“堅持”“主張”“供給”“贍養(yǎng)”等。
maintain衹用作及物動詞,後麪可接表示生命、法律、秩序、和平、友誼等名詞作賓語; 也可接that從句,還可接以“to be+ adj .”充儅補足語的複郃賓語。

(CONTINUE TO HAVE) to continue to have; to keep in existence, or not allow to become less
(KEEP IN GOOD CONDITION) to keep a road, machine, building, etc. in good condition
(EXPRESS) to express firmly your belief that something is true
(PROVIDE) to provide someone with food and whatever is necessary for them to live on

If you maintain something, you continue to have it, and do not let it stop or grow weaker.
If you say that someone maintains that something is true, you mean that they have stated their opinion strongly but not everyone agrees with them or believes them.
If you maintain something at a particular rate or level, you keep it at that rate or level.
If you maintain a road, building, vehicle, or machine, you keep it in good condition by regularly checking it and repairing it when necessary.
If you maintain someone, you provide them with money and other things that they need.
