What does citrous mean?
Citrous is an adjective meaning relating to, belonging to, or resembling the genus Citrus — the group of trees and shrubs that produce oranges, lemons, limes, grapefruits, and similar fruit. It carries two closely linked senses: a botanical one, describing plants or crops of the citrus kind, and a sensory one, describing the sharp, fresh, acidic flavour and fragrance typical of these fruits. In practice, citrous turns up most often in food, wine, and horticultural writing, as in 'a citrous dressing' or 'a wine with citrous notes'. It is largely interchangeable with the far more common adjective use of its root word, and many dictionaries treat the two as variants; because it is less frequent, it can lend a slightly formal or literary tone. The word derives ultimately from the Latin citrus, the classical name for the citron tree, which also gives us citron and citrine.
adjectiveOf, relating to, or belonging to the genus Citrus; having the qualities of citrus fruit such as lemons, oranges, limes, and grapefruits.
- Relating to or belonging to the genus Citrus (trees bearing oranges, lemons, limes, grapefruits, etc.).
- Having the characteristic sharp, fresh flavour or scent associated with citrus fruit.
"The salad was brightened by a sharp citrous dressing of lemon juice and olive oil."
"The orchard specialised in citrous crops, mainly blood oranges and Meyer lemons."
"A crisp white wine with pronounced citrous notes paired beautifully with the seafood."
'Citrous' is essentially 'citrus' wearing its adjective hat — same Latin root, but reserved for describing that sharp, sunny tang in food and wine writing.

Etymology of citrous
Citrous derives from the Latin citrus, the name the Romans gave to the citron tree, whose fragrant wood and fruit were prized in antiquity. English borrowed the base as 'citrus', and citrous arose as a straightforward adjectival formation from it. The same Latin root underlies related words such as citron (the thick-rinded citrus fruit) and citrine (the pale yellow gemstone named for its citrus-like colour). Citrous has long been treated as a variant adjective of citrus rather than an independent term.
