the word 'stood' is the past tense and past participle form of the verb 'stand,' which means to come to an upright position after previously being in a prone or seated position. This term can also be used to refer to the act of proving one's point in an argument or debate.
when used to refer to position, the verb is always conjugated to agree with the subject of the sentence (e.g. She stands./She stood.). When used to refer to point-making, the verb is never conjugated in its present or past participle form.
1. I stood in line at the store for hours waiting to buy the new video game.
2. We stood our ground in our argument and refused to back down.
3. He stood up for what he believed in and made an impassioned argument.
the verb 'stand' is often used in compound forms, where two verbs become joined together to mean something other than the usual (e.g. I stood up for him in the meeting.). The verb can also be used in a figurative sense to refer to a state of affairs or opinion (e.g. Their service always stands out to me.). The verb can also signify refusal (e.g. She couldn't stand the thought of having to apologize.).
