===Impersonal/Passive Voice===

Gaelic verbs don't technically have a [[Passive (definition)|Passive]] verb form. Instead the passive is typically represented through a [[Periphrastic (definition)|periphrastic]] construction using the verbs ''Rach'' or ''Tha'' + the passive marker ''air''. It does, however, have an [[Impersonal (definition)|impersonal]] form. The '''Impersonal''' is used to indicate an indeterminate subject. ''bhatar mi'  means "I was been"

Since Gaelic doesn't distinguish between subject and object pronouns (unlike it's sibling [[Modern Irish]]), it is very difficult to determine if these pronouns are subjects or objects. We list them here as if they were subjects, with the understanding that the pronouns in the following tables represent the logical objects of the verb

#The pronoun ''tu'' is used here instead of ''thu''
#The 1st person plural has a special inflected form, which like the first person singular is never used with a pronoun. This 1st person plural form is rarely used anymore.

In English these are translated with by just the verb "Hear!". 1st and 3rd person imperatives translated loosely as "Let me be", "let us be", "let he/she/them be".
