Petioalr → It is derived from 'petiolus' (meaning little foot or stalk) in Latin, which refers to the stalk of a leaf. The suffix '-ar' is used to form adjectives. Thus, 'petiolar' describes something related to or resembling a petiole, the stalk that attaches a leaf to a stem.
Think of the 'little stalk' ('petiolus') that connects a leaf to a stem, and remember that 'petiolar' refers to something related to that stalk.
