Built from

man — root · think, mind
From PIE *men-, the root of cognate Sanskrit manas, Greek menos, Latin mens, English mind. The concrete imagery is mental grasping or holding in consciousness.
as — stem · noun formant (neuter/masculine)
The ancient n-stem suffix (*-es-) found also in Sanskrit and Latin, forming abstract nouns. Here the noun is treated as masculine in Pali grammatical tradition.
i — ending · locative singular
The locative case ending -i on an n-stem noun, marking the location 'in the mind' or 'in thought'. In the phrase manasi karoti 'bears in mind', it expresses the mental ground of action.

Etymology. From Proto-Indo-European *men- 'to think, to mind', the root underlying Sanskrit manas, Greek menos 'spirit, courage', Latin mens 'mind', English mind. The Pali form preserves the ancient neuter n-stem noun, here inflected in the locative singular (manasi 'in the mind') to express the local sense 'in thought', 'in mental attention'.
