O.E.
þis, neuter demonstrative pronoun and adj. (masc.
þes, fem.
þeos), probably from a North Sea Gmc. pronoun formed by combining the base
*þa- (see
that) with
-s, which is probably identical with O.E.
se "the" (representing here "a specific thing"), but it may be O.E.
seo, imperative of
see (v.) "to behold." Cf. O.S.
these, O.N.
þessi, Du.
deze, O.Fris.
this, O.H.G.
deser, Ger.
dieser. Once fully inflected, with 10 distinct forms (see table below); the oblique cases and other genders gradually fell away by 15c. The O.E. plural was
þæs (nom. and acc.), which in Northern M.E. became
thas, and in Midlands and Southern England became
thos. The Southern form began to be used late 13c. as the plural of
that (replacing M.E.
tho, from O.E.
þa) and acquired an
-e (apparently from the influence of M.E. adj. plurals in
-e; cf.
alle from
all, summe from
sum "some"), emerging early 14c. as modern
those. About 1175
thes (probably a variant of O.E.
þæs) began to be used as the plural of
this, and by 1200 it had taken the form
these, the final
-e acquired via the same mechanism that gave one to
those. | Masc. | Fem. | Neut. | Plural |
