cilantro

The word 'cilantro' entered English directly from Spanish in the early 20th century, reflecting the influence of Mexican cuisine. The Spanish 'cilantro' itself evolved from Late Latin 'coliandrum', a variant of Latin 'coriandrum', which was borrowed from Greek 'koriannon'. The Greek term is likely of Pre-Greek, non-Indo-European origin, suggesting the herb's ancient cultivation in the Mediterranean region. The modern English usage specifically for the fresh leaves, distinct from the dried seeds (coriander), was cemented through its prominence in American culinary contexts.

This word is a direct borrowing from Spanish. It does not contain separable morphemes within the context of modern English.
