Perfect verb tense is used to show an action that is complete and finished, or perfected. This tense is expressed by adding one of the auxiliary verbs — have, has, or had — to the past tense form of the main verb. For example: I have seen the movie that was nominated for an Academy Award.

a phrase is a set of word that make a sense, an expression formed by two or more words.

" teacher´s dictum on the possession of human "

" made a pile practicing "

" lived to an impressive age and dies "
