Capitalising Italian pronouns

Ciao,

I would like to ask if "io" has to be capitalised at the start of a sentence or should it remain as it is even if it is at the start of the sentence?

For example, "io amore  di mangiare gelato".

Grazie.

Ciao jingling,

Yes, every word (be it a pronoun, an adjective, a noun, a verb etc.) must be capitalized at the beginning of a sentence. This however occurs only after full stops, new lines of texts, exclamation marks and question marks.

Consider these:
Io amo (amore is a noun, not a verb - amare) mangiare il gelato.
"Io" is here capitalized because it introduces a new line of text.
Tu ami mangiare il gelato, io amo mangiare la cioccolata.
"Io" isn't capitalized here, because it follows a comma.

The only exception to this rule is the formal pronoun Lei. You can either capitalize it or not (if you decide not to, the rules above apply: at the start of a sentence it must always be capitalized). Capitalizing it in the middle of a sentence makes it a bit more formal - this form is the standard in business writing and cover letters, for example.

Hope this helps! :)
