The Spanish word "amor" (meaning "love") comes directly from the Latin word "amor" with the same meaning. The Latin "amor" was formed from the verb "amare" ("to love") combined with the suffix "-or", which was used to create nouns indicating the result or effect of an action. So "amor" literally represented the result or state of loving.

Several common Spanish words are related to "amor", including the verb "amar" (to love), "amante" (lover), "amable" (kind, friendly), and "amistad" (friendship). All these words share the same Latin root "amare" and express different aspects of love and affection.

While English "love" comes from a different root, there are several English words related to Spanish "amor", including "amorous" (showing romantic love), "amateur" (originally meaning "lover of" something), "amiable" (friendly, pleasant), and "amity" (friendship). These words entered English through French, but ultimately trace back to the same Latin root "amare".
