Hello,<br/><br/>Could you please suggest whether an indefinite article is<br/><br/>necessary in the phrase "to be of [<b>a</b>?] great use"?<br/><br/>I do not see any reason to instantiate "use" so I would omit<br/><br/>an article. On the other hand, abstract nouns modified by<br/><br/>adjectives are sometimes preceeded by an indefinite article.<br/><br/>So, there is the truth?<br/><br/>Thanks in advance.<br/><br/>--<br/><br/>Victor
