Synonyms for the
late Old English þe, nominative masculine form of the demonstrative pronoun and adjective. After c.950, it replaced earlier se (masc.), seo (fem.), þæt (neuter), and probably represents se altered by the þ- form which was used in all the masculine oblique cases (see below).
Old English se is from PIE root *so- "this, that" (cf. Sanskrit sa, Avestan ha, Greek ho, he "the," Irish and Gaelic so "this"). For the þ- forms, see that.
The s- forms were entirely superseded in English by mid-13c., excepting dialectal survival slightly longer in Kent. Old English used 10 different words for "the" (see table, below), but did not distinguish "the" from "that." That survived for a time as a definite article before vowels (cf. that one or that other).
Adverbial use in the more the merrier, the sooner the better, etc. is a relic of Old English þy, originally the instrumentive case of the neuter demonstrative þæt (see that).
