The Spanish verb 'parcelar' (to parcel out or divide into plots) comes from the Spanish noun 'parcela' (parcel, plot of land), which was borrowed from French 'parcelle' (parcel). The French term derives from Latin 'particella', meaning 'small part', which is a diminutive form of Latin 'pars' (part). The Spanish verb was formed by adding the common verb-forming suffix '-ar' to 'parcela'.

This etymology shows how the original Latin concept of a 'part' or 'small part' evolved to specifically refer to a plot of land or portion of territory, and then developed into a verb meaning to divide something into such portions.

Some related and simpler Spanish words include 'parte' (part) and 'parcial' (partial), which also derive from Latin 'pars'. While 'parcelar' specifically refers to dividing into plots or parcels, these related words maintain the more general meaning of 'part' or 'portion'.

English speakers can easily connect 'parcelar' to the familiar word 'parcel', which shares the same etymology through French and Latin roots. The English 'part', 'partial', and 'particle' are also related, all ultimately deriving from Latin 'pars'. Just as 'parcelar' means to divide into parcels in Spanish, English uses phrases like 'to parcel out' with the same meaning.
