For --The word translated as "for" introduces a reason or explanation so "because" and, in questions, "why." However, since this word always appears in the second position, it is more like an aside remark like, "consequently" or "as a cause." 

ye-- This is from the second-person, plural form of the verb.

have -- The word translated as "have" means to "have," "possess," "bear," "keep close," "have means to do,"  "to have due to one," or "keep" and many specific uses.

the -- The word translated as "the" is the Greek definite article, without a noun, it has the sense of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more. 

poor  - "Poor" is from an adjective, used as a noun, which means "beggaring", and "beggarly." The sense is "the begging. Christ uses this term a number of times, and through it, he gives a clear sense of the role that beggars play in the world. The first time he uses the word is it in the context of being "beggars of spirit,"that is, lacking spirit in the Beatitudes and throughout the Gospels, Christ separates beggars into two types: those who are spiritually afflicted and those that are physically incapacitated.

always  - The word translated as "always" means "at all times" but what makes it interesting is that Christ seldom uses this word but it occurs twice in this verse.  This word actually starts the sentence.

with - "With" is from the Greek word that is almost always translated as "with" or a related concept such as "among" or "by the means of". - 

you;  - The word translated as "you" does not mean "you." It is the reflexive pronoun, "themselves." It can be combined with a second person pronoun to means "yourselves" but there is no such pronoun here. Typically, another Greek word (autos) is used to create the reflexive for the first and second person. However, this translation is as "with you" goes back to the Latin Vulgate and it is continued in all other Biblical translations. The sense, just reading the words, is "among themselves" or"by means of themselves."

but  - The Greek word translated as "but" joins phrases in an adversarial way. Since it always falls in the second position, translating it as "however" often captures its feeling better. When used in writing, it creates complex sentences, but when spoken, it makes a good pausing point so that an important or humorous word can follow.

me  - "Me" is the regular first-person pronoun in Greek.

ye-- This is from the second-person, plural form of the verb.

have -- The word translated as "have" means to "have," "possess," "bear," "keep close," "have means to do,"  "to have due to one," or "keep" and many specific uses.

not - the Greek word translated as "not" is the Greek negative used to deny objective facts, not opinions. It makes a negative statement of fact. Adding "really" to the sentence captures the same idea.

always. The word translated as "always" means "at all times" but what makes it interesting is that
Christ seldom uses this word but it occurs twice in this verse. Most people uses the terms "always" whenever they discuss something that it done frequently. Christ never makes this mistake. This word actually starts the sentence.
