enhance: [14] To enhance something is literally to ‘make it higher’. The word comes via Anglo- Norman enhauncer from Old French enhaucer, a descendant of Vulgar Latin *inaltiāre ‘raise’. This was a verb formed from the Latin intensive prefix in- and the adjective altus ‘high’ (source of English altitude). This original literal sense persisted into English (‘It was a stone, the which was enhanced upright’, William Caxton, Charles the Great 1485), but had largely died out by the end of the 16th century, leaving the field clear for the metaphorical ‘augment’.

toast: [14] Toast comes via Old French toster ‘roast, grill’ from Vulgar Latin *tostāre, a derivative of the past participle of Latin torrēre ‘parch’ (source of English torrid). Its use as a noun, meaning ‘toasted bread’, dates from the 15th century. It was common to put sippets or croutons of spiced toast into drinks to improve their flavour, and it was the custom of gallants in the 17th century, when (as they frequently did) they drank the health of ladies, to say that the name of the lady in question enhanced the flavour of their drink better than any toast.

That is supposedly the origin of the use of the term toast for ‘drinking someone’s health’.

enhance (v.)youdaoicibaDictYouDict
late 13c., anhaunsen "to raise, make higher," from Anglo-French enhauncer, probably from Old French enhaucier "make greater, make higher or louder; fatten, foster; raise in esteem," from Vulgar Latin *inaltiare, from Late Latin inaltare "raise, exalt," from altare "make high," from altus "high" (see old). Meaning "raise in station, wealth, or fame" attested in English from c. 1300. Related: Enhanced; enhancing.

The -h- in Old French supposedly is from influence of Frankish *hoh "high." The -n- perhaps is due to association with Provençal enansar, enanzar "promote, further," from enant "before, rather," from Latin in + ante "before."
