mais[1]
Etymology
It is inherited from Old French mais, inherited from Latin magis (“more; rather”).[2][3][1] “Magis” meant “more”, but unlike plūs, which expressed number and quantity, it usually had the qualitative sense “rather”; it served to form periphrastic comparatives, as in “magis sanus” “healthier”.[4] It was joined to sed (“but”) in “sed magis” “but rather”, and, from there came to be used alone as an adversative conjunction, replacing “sed” in spoken Latin and in all the Romance languages.[4][3] Rey thinks it probably adapts an older “*mais”, known in Oscan, under the influence of magnus (“great”).[4]
Cognate with Italian ma, Italian mai, Spanish mas, Portuguese mas and Occitan mais; Romanian mai has only the Latin sense “more”.[3][5]
Earliest recorded meaning
In the second half of the 10th century mais is found both as an adverb of time, in ja non… mais “never again”, and as a conjunction introducing an idea contrary to one already expressed, in the Vie de saint Léger.[6]
Semantic evolution
In Old French mais was still an adverb of quantity, “more” (late 10th century), and of time, “from now on” (mais + future, about 1100) or ne… mais “no longer” (about 1050).[6][4] These senses survive in compounds such as jamais and désormais and in the old phrase n'en pouvoir mais “to be unable to help it” (about 1160), where mais still means “more”.[6][3][7] In comparison, plus ousted it in French, though Spanish kept más.[4]
The conjunction marks contradiction, restriction or objection, and at the head of a sentence a transition or surprise (mais enfin !).[7][8]
