Morphology

helianthus + annuus

This is a compositional Latin binomial: 'Helianthus' identifies the sunflower genus and 'annuus' means 'annual' (occurring yearly). A learner who knows both constituent meanings can directly infer 'annual sunflower' (the common sunflower), so the name is transparent rather than idiomatic.

Etymology

Helianthus annuus comes from old words meaning 'sun' and 'flower', and 'annuus' means 'yearly'. Sunflowers often turn to face the sun, so this name gives a clear picture of a sun-loving, one-year plant commonly grown for seeds and oil.
