Blessed -- (CW) The word "blessed" in Greek is an adjective from a root word meaning "happy" or "fortunate." In Jesus's era, all luck was attributed to divine favor but this is not otherwise a religious word. It has no relationship to the Greek verb "bless" or the noun "blessings." This word can also mean "wealthy". This sets up an interesting play on words that only works in Greek, saying "wealthy the poor,"

be -- (WN) There is no verb "be" in the Greek source. It is implied by the equating of "workman" with "worthy" both in the Greek form of subjects. This word should not singular but plural because the words it joins are plural.

ye -- (WW) The word translated as "the" is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this", "that", "these", "those"). See this article for more. There is no vocative definite article, (despite being shown in Perseus). When the vocative is meant, no article is used or they used two other letters.

poor -- (CW)  The Greek word translated as "poor" means "a beggar." It is the subject of the phrase and plural, "beggars." The first two words are literally, "Lucky these beggars."

for -- The "for" here is a causal adverb that means "seeing that", "because", or "since."

yours -- - (WF)The term translated as "your" is not the common pronoun, but a special term that refers to a group of people, "your people," "your goods," and "your household."Jesus uses it only four times in the Gospels. It is not the common pronoun usually translated as "your." Here it is neuter, plural meaning "your things." This doesn't refer to people, but things.

is  --  The verb "is" here is the common form of "to be" in Greek. It means to have a certain characteristic or remain in a certain condition. It also equates terms or assigns characteristics.  With an object in the possessive form the "is" becomes "is of," which can mean "it is descended from," "it is the type of," "it belongs to," "is made of," "is a duty of," "is at the mercy of," or " is dependent on."  Though it is singular, a plural group of things used a single verb as a single things.

the -- The word translated as "the" is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this", "that", "these", "those"). See this article for more. 

kingdom -- The word translated as "kingdom" can be the region, the reign, the castle or the authority of a ruler. Christ does not seem to use it to mean a physical region, so its translation as "reign" or "realm" seems more appropriate. This is especially true because the "reign" of a king means the execution of his will.

of -- This word "of"  comes from the genitive case of the following word that required the addition of a preposition in English.  The most common is the "of" of possession, but it can also mean "belonging to," "part of", "which is", "than" (in comparisons), or  "for", "concerning" or "about" with transitive nouns. 

missing "the/this"  -- (MW) The untranslated word is the Greek definite article," the," which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," and "those"). See this article for more. 

God. -- The word translated as "God" means "God" and "deity." It is introduced with an article, so "the God," "the Divine" or "the divine one." Jesus often uses it this way perhaps to indicate the one God as opposed to the pagan gods.
