When should I use "as part of", and when "as a part of"?

The difference between "as part of" and "as a part of" is essentially the difference between part and a part.

As part of this community, I feel the need to express my opinion.

Your comment is useless, as a part of my recent comments is.

In the first case, part is used with the meaning an element or constituent that belongs to something and is essential to its nature. In the second case, part is used to mean a piece or segment of something such as an object, activity, or period of time, which combined with other pieces makes up the whole.

Other phrases uses part, and would have a different meaning (or no meaning) if they would use a part.

We have come here to take part in a major game. (Take part means join in.)

As a native speaker, I disagree with this answer. I do not feel that the article "a" emphasizes how the part in question is essential to the whole. –  Mr. Shiny and New 安宇 Oct 29 '12 at 14:49
@Mr.ShinyandNew安宇 could you please provide your answer or opinion? I'm really confused with this cause for me the word "part" is a countable noun so it can't be used without a determiner. But recently I began to spot that a lot of native English speakers use it without one, simply "part" –  user907860 Jun 12 at 22:00
@Dmitry You could ask that question on [ELL](ell.stackexchange.com). This ancient comment thread isn't really the place to discuss it. –  Mr. Shiny and New 安宇 Jun 13 at 0:53

It depends on the speaker/writer. If the part can be separated from the whole, use "a part."

Hi english lover Your answer is not very clear. Could you explain more what you mean and why it is correct? –  nxx Mar 6 at 13:51

Actually, the person who mentioned countability was close to the mark.

It is a question of whether we can predict the size or number of parts.

If we can predict it, then we use a qualifier; otherwise, no quantifier.

Note that articles (a, an, the) are quantifiers; also words such as "some", "any", "no", etc.

There's probably a better term than "predictable", but I think you get the drift.

Part is used as both countable and uncountable, an example of the first case is

We spent part of our time fighting and arguing.

But there is a tendency to use part in the plural when it is treated as uncountable and that's why we seldom find "a part of" (but we can of course use "the part"). Example:

Both parts are severely damaged.

I don't think you grasp 'countability' correctly; and this doesn't really respond to OP's question. –  StoneyB Oct 2 '12 at 0:54
