Frances Karttunen: 

MACHŌ to know something /saber algo (M) nonact. MAT(I)MAT(I) vt; pret: MAH – MAT There are many lexicalized constructions built on MAT(I), and in many cases it is difficult to distinguish derivations from MAT(I) and derivations from IHMAT(I) ‘to know how to do things deftly, cleverly.’ In their extensive glossing of this item both M and S intersperse derivations from both of these. MAT(I) used reflexively can mean ‘it seems, it is thought that …,’ and when this is in other than in third person, as in ‘It seems to me,’ the subject prefix is omitted, hence NOMAT(I) rather than NINOMAT(I). ONMAT(I) with the directional particle ON- means ‘to know the way to a place.’
