Please don’t ask why, but there are some weird rules for the capitalisation of titles. Even though nobody can really make sense of these rules, we like to stick with them anyways to conform to the use of titles on other sites that follow these rules. the rules are as follows:
- The first and last words are always capitalised.
- All nouns and active verbs should be capitalised.
- Articles (a, an, the), conjunctions (and, but, or, nor) and up to four-letter prepositions (as, at, by, for, from, in, into, of, off, on, onto, out, over, to, up, with) are always lower-case, unless they are the first or the last word.
- As is only lower-case if it is followed by a noun.
- Five (or more) letter prepositions (across, among, beyond) are capitalised.
- These words are capitalised: also, be, if, than, that, thus, when and as (if it is followed by a verb).
- Phrasal verbs need to be capitalised. Phrasal verbs combine verbs and prepositions or adverbs into an idiomatic expression whose meaning differs from that of the actual definitions of the individual words used. Examples: Beat Up, Come Back, Do Over, Leave Out, Try Up, etc.
