Tense of the verb tells <u>when(</u><u>time </u><u>of </u><u>an </u><u>action</u><u>)</u> an action is done. There are three tenses of the verbs: <u>past</u> tense, <u>present</u> tense, and the <u>future</u> tense. Past tense tells about actions that happened in <u>the </u>past. <u>“</u><u>W</u><u>a</u><u>s</u><u>”</u> or <u>“</u><u>w</u><u>e</u><u>r</u><u>e</u><u>”</u> are added <u>before </u><u>the </u><u>main </u><u>verbs</u> to change it in past tense. Present tense tells about actions that are <u>currently</u><u> </u><u>happening in the </u><u>present</u>(did some changes to the question). We add <u>“</u><u>i</u><u>s</u><u>”</u> or <u>“</u><u>a</u><u>r</u><u>e</u><u>”</u> to change the verb into present tense. Future tense tells about actions that <u>will </u><u>happen</u><u> </u><u>in </u><u>the </u><u>future</u>. Adding <u>“</u><u>will”</u> or <u>“</u><u>s</u><u>h</u><u>a</u><u>l</u><u>l</u><u>”</u> to the verb will change it in future tense.

An antagonist is a person who actively opposes or is hostile to someone or something. So in Shakespeare's Romeo and Juliet the Capulet's are the Montague's antagonist due to the long family feud between the two rival families.
