The first translation that you cite for the word — accessories, articles, gear; — is correct only of the plural noun “принадлежности.”

The second meaning – belonging (to), affiliation (with); – is correct only in the verb form of this word, as you explained it in your blog.

The third meaning – characteristic, attribute -is the trickiest usage of this word. If you just wish to translated the word “attribute, characteristic, property” into Russian, you should use “своиство.” The word «принадлежность» in the singular noun form becomes applicable only when speaking about a characteristic of a specific object within a specific context. «Принадлежность» is a combination of the prepositions “при” [with, in the surroundings of], “над” [above, before, over] and the verb “лежать” [to lay, v.] Together, the meaning of the word mutates to “its/his main purpose here is. . .” -> as in «принадлежность этой вещи/этого человека . . .» The implication is that the same object in a different context will have a different “принадлежность”.

Whew. . . Explaining Russian language is tough! I hope this will helpful to you in furthering your understanding of Russian.

If you wish to use the diminutive case on the word “Lenin,” it would probably sound more like “Lenichka” or “Lenishka,” but not Leninchik. I am only a native speaker, not a Russian teacher, so forgive me if my explanation is awkward:

I feel that Leninchik sounds wrong because of the awkward accent in this word. For example, in the word “ГОлубь”, the accent falls on the first syllable, just as in the word ЛEнин. In the diminutive, the accent falls on the second syllable “ГоЛУбчик,” but in the word “ЛеНИнчик,” the accent ought to fall on the second syllable. However, if you try pronouncing it that way, you’ll immediately feel the awkwardness and loss of the word “Ленин.” To preserve the accent on the first syllable, the diminutive ending would change to “-чка,” or “нька,” as in converting the male name “Миша” to “Мишенька.”

Then again, you can take this grammar discussion into another realm entirely based on the origin of the word Lenin, which comes from the river Lena, and literally means “of Lena.” If you are trying to make a diminutive adjective, then the correct word would be “Lenochkin.”

and one more note: «эти штаны моя принадлежность» doesn’t work for two reasons: штаны and принадлежности are always plural. So there is really only one way to say it: «эти штаны принадлежат мне».
