Mhí

mhí is the Irish word for "month." It is the lenited form of mí, used after the definite article to mean "the month" (for example, an mhí seo = this month). Without the article, mí functions as the indefinite form meaning "a month" or, in some contexts, "months" in a general sense.

In everyday usage, mhí appears in time and calendar expressions. Common phrases include an mhí seo (this month) and i mí Eanáir (in January). When referring to months in a general sense or listing them as a category, the plural form míonna is used, as in míonna na bliana (months of the year).

Morphology and spelling notes: mí is a masculine noun. Like many Irish nouns, it undergoes lenition when preceded by the definite article, producing an mhí from mí. The form is typically reserved for phrases that specify a particular month; the month names themselves (Eanáir, Feabhra, Márta, etc.) are used without mhí when stated as calendar entries, though they may appear in expressions that require a noun phrase with a determiner.

Overall, mhí is a basic unit in Irish timekeeping, functioning as the standard word for a month when paired with the definite article and as the general concept of a month in its indefinite form.
