Mí is a pronoun meaning "me". It's always preceded by a preposition. It has a written accent.

Is there an accent in MIS?

The difference between mi without an accent mark and mi with an accent mark lies in their purpose. Mi, without the accent mark is a possessive determiner, like “my,” as in “my dog,” “my family,” or “my hair.” The mí with the accent attached means “me,” and we use it after prepositions, so it is a prepositional pronoun.

What letters can have accent marks?

The most common accents are the acute (é), grave (è), circumflex (â, î or ô), tilde (ñ), umlaut and dieresis (ü or ï – the same symbol is used for two different purposes), and cedilla (ç). Accent marks (also referred to as diacritics or diacriticals) usually appear above a character.
