It is the negative form of the verb commonly translated as "can," which means  "to be able to do," "to have the power to do."  While the form of the verb could be the second person future, "you are going to be unable to do nothing," this double negative would really mean "you are going to be unable to do anything."

ἀετοί. [2 verses](noun pl masc nom) "Eagles" is aetos, which means "eagle," (which was considered a bird of omen) "eagle as a standard (of the Roman legions)," and "omen."  - Eagles" is from the Greek word for "eagle," "bird of omen," or "omen." It is a Greek word, but this word was used in the Septuagint to translate the Hebrew word for "eagle" (nesher), which means both "eagle" and "vulture." Among the Jews, it was forbidden to eat eagles, along with buzzards and vultures, so they were grouped among carrion birds. Some uses of this word, such as Micah 1:16, which refers to the baldness of eagles, clearly referring to vultures, which are bald. (Bald eagles, of course, are not bald but have white feathers on their adult heads and were not known in the ancient world.) While there are positive characteristics of eagles in Jewish writing, based on their size and strength. This view of eagles in the West is positive, but this comes from Greek and Roman culture, which had a very positive view of the bird, but they also saw eagles as a bird of omen.

ἀγαλλιαθῆναι [3 verses](verb aor inf pass) "To rejoice" is agalliao means "rejoice exceedingly" and is a later form of agallomai, which means to "glorify," and "exalt," especially the idea of "paying honor" to God. - -- The verb translated as "rejoiced", which literally means "much leaping" and generally, to "celebrate." Jesus uses it only three times. This word doesn't appear in non-biblically influenced Greek. It appears first in the Greek OT where it translated many different Hebrew words that mean "rejoin," "be glad," "shout," "exalt,"  and so on. This word is a version of a more common Greek word that means "glorify," and "exalt," but the Judean use of this word seems broader.

Jesus uses another word. Jesus uses another word, phileô, which means "to love," "to like," "to be fond of doing," and "to show affection" to express "love" in the sense of like and dislike. He never uses the word eros, which describes romantic, sexual love. -- (CW) The word translated as "love" expresses a lot of different ideas including "to care for," "to be fond of," "to greet with affection," "to persuade," and "to be contented with." Jesus however, applies it to relationships where we have a duty to care for others: family, God, etc. Another word, also translated as "love," is used to for relationships of affectionate friendship that are more voluntary. To distinguish this word, translating it as "cares for" seems to work best. See this article on love for more information.
