The Spanish verb 'enamorar' (to fall in love) is constructed from three main elements: the prefix 'en-' meaning 'inward' or 'into', the noun 'amor' (love) which comes directly from Latin 'amor', and the verbal suffix '-ar'. When combined, these elements literally create the concept of 'going into love' or 'becoming filled with love', which evolved to mean 'to fall in love' in modern Spanish.

The most obvious related Spanish word is 'amor' (love), which is both simpler and more commonly used. This noun forms the core of 'enamorar' and is used in many romantic contexts. Other related words include 'amoroso' (loving), 'amante' (lover), and 'amar' (to love) - all of which share the same Latin root 'amor'.

While English took a different path for its main words about love (using Germanic roots), we do have several words from the same Latin 'amor' root. These include 'amorous' (full of or showing love), 'paramour' (a lover, from French 'par amour' meaning 'through love'), and 'amateur' (originally meaning someone who does something for the love of it, rather than professionally).
