Did you know?

Where does the phrase just deserts come from?

Why do we say that someone has gotten their just deserts? Does this turn of phrase have anything to do with dessert (“a sweet food eaten at the end of a meal”) or desert (“a dry land with few plants and little rainfall”)? In fact, the phrase employs neither of these words. Instead, it uses a completely unrelated word that happens to be pronounced like the word for sweets and spelled like the one for a dry place: desert, meaning “reward or punishment deserved or earned by one’s qualities or acts.” This little-used noun is, as you might have guessed, related to the English verb deserve. It has nothing to do with arid, dry land, or with cookies and ice cream.

Word History

Etymology

Noun (1)

Middle English, "barren expanse of land (either wooded or arid), wasteland," borrowed from Anglo-French & Latin; Anglo-French, borrowed from Latin dēserta "unfrequented places, wilderness," noun derivative from neuter plural (feminine singular in Late Latin) of dēsertus "empty of people, uninhabited" — more at desert entry 2

Adjective

Middle English desert, deserte "barren, uninhabited, deserted, forsaken," borrowed from Anglo-French & Latin; Anglo-French, borrowed from Latin dēsertus "empty of people, uninhabited," from past participle of dēserere "to part company with, abandon, leave uninhabited" — more at desert entry 3

Verb

borrowed from French déserter, going back to Old French, "to devastate, make uninhabited, abandon, leave," borrowed from Late Latin dēsertāre "to leave, abandon," frequentative of Latin dēserere "to part company with, abandon, leave uninhabited, leave in the lurch," from dē- de- + serere "to link together, join in a series" — more at series

Note: Note that Dictionnaire du Moyen Français divides deserter into two lemmas, assigning the senses "devastate, make uninhabited" to a derivative of desert "barren, uninhabited" (see desert entry 2) and the senses "abandon, leave" to a loan from Late Latin dēsertāre.

Noun (2)

Middle English desert, dissert "fact of deserving reward or punishment, worthiness, merit," borrowed from Anglo-French desert, deserte, desserte "merit, reward, fact of deserving reward or punishment, wrongful conduct, reason, cause" (also continental Old & Middle French), derivative of deservir "to deserve, merit, earn, be entitled to" — more at deserve

Note: The derivation of Old French desert from deservir has been variously explained. Trésor de la Langue Française describes desserte as formed from the present tense base (i.e., the base lacking -v-) of desservir ("Déverbal, formé sur le radical du présent de l'indicative de desservir"). P. Ruelle points in a different direction, judging both the Old French noun deserte and the adjective desert as a variant of the past participle deservi, descending from *desérvitum, a presumed by-form of classical dēservītum (see his "Notes sur le lexique des Isopets," Romania, vol. 101, no. 401 [1980], pp. 77-78).
