And -- The Greek word translated as "and" is used as the conjunction "and," but it also is used to add emphasis ("also").

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

say, -- The word translated as "Say" is the most common word that means "to say," and "to speak," but it also means "to teach," which seems to be the way Christ uses it more frequently. It also has many ancillary meanings such as "to count" ("to number" or like we might say, "to recount" a story) or "to choose for yourself."

If  - The "if" here expresses a condition but it means nothing regarding whether that condition is met or not. It also means "if ever" and "whenever."

we -- This is from the first-person, plural form of the verb.

had  - (WT) This helping verb "had" indicates that the verb is the tense indicating an action completed in the past. This is not the tense of the verb here, which is the simple past.

lived -- (WW)  -   - "Lived" is a Greek verb that means to "be seated," "sit," especially of courts, councils, assemblies, etc.  The sense of being put in a position of authority as we would say "chair." It also means to "sit still" or "sit idle."

in   -- The word translated as "in" means "in," "within," "with," "during" (time),  or "among"  with a dative object as the one here. 

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. 

days  - The Greek word translated as "days" also means "time," in general, and refers specifically to the "daytime."

of -- This word "of"  comes from the genitive case of the following word that requires the addition of a preposition in English.  The most common is the "of" of possession.

our -- The "our" is the plural possessive first-person pronoun. This pronoun follows the noun so "of ours."

missing "the"  -- (MW) The untranslated word 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. 

ancestors,  - "Ancestors" is the common word meaning "father" that Jesus uses to address his own father, though it can mean any male ancestor. Here, the sense is forefathers.

we -- This is from the first-person, plural form of the verb.

would -- "would" is a particle used with verbs to indicate that the action is limited by circumstances or defined by conditions. There is no exact equivalent in English, but it is translated as "possibly," "would have," "might," "should," and "could." This particle usually suggests the subjunctive form of the verb that doesn't appear here.

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. If it precedes the verb, it negates the clause, but here it precedes the "would," negating only that concept.

have - (WT) This helping verb "had" indicates that the verb is the tense indicating an action completed in the past. This is not the tense of the verb here.

taken part -- (WW) "Taken part" is a Greek verb that means to "be seated," "sit," especially of courts, councils, assemblies, etc.  The sense of being put in a position of authority as we would say "chair." It also means to "sit still" or "sit idle." This is a good example of how the confusing translation of "partakers" in the KJV leads a worse translation in the NIV. The NIV translators were clearly rephrasing the English of the KJV not translating the Greek.

with -- -- (CW) This word "with"  comes from the genitive case of the following word that requires the addition of a preposition in English.  The most common is the "of" of possession. However, it can also mean "belonging to," and "part of," which is the sense here.

them  -  -- The word translated as "them" is the Greek word commonly translated as third-person pronouns in English.

in -- (IW) There is nothing that can be translated as "in" in the Greek source.

shedding - (WW, WF) The Greek word translated as "shedding" means "a partner," "a comrade," "a companion," and "a sharer of anything." It is from the Greek word meaning "common." Jesus only uses this word here, in this verse. It is in the same form as the subject of the sentence, so it is equated with the subject "we." Itis a noun, not a participle.

in -- The word translated as "in" means "in," "within," "with," "during" (time),  or "among"  with a dative object as the one here. 

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. 

blood  - "Blood" is from the Greek word that means "blood," "bloodshed," and "kinship." Clearly, it is used here because of the double meaning of bloodshed and kinship.

of -- -- This word "of"  comes from the genitive case of the following word that requires the addition of a preposition in English.  The most common is the "of" of possession.

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. 

prophets.  - -- -- (UW) The Greek word translated as "prophets" means "one who speaks for God," "interpreter" and was the highest level of priesthood in Egypt. Christ uses it to refer not only to divine spokespeople, but their books in the OT. It is from the verb that means "to shine before."
