The Spanish verb 'recelar' (meaning 'to suspect' or 'to distrust') comes from combining two Latin elements: the prefix 're-' (meaning 'again' or 'back') and the verb 'zelari' (meaning 'to be jealous'). The Latin 'zelari' first evolved into the Spanish 'celar' (meaning 'to be jealous' or 'to conceal'), and then the addition of 're-' created 'recelar', implying a recurring or intensified sense of jealousy or suspicion.

A simpler related Spanish word is 'celar', which means 'to be jealous' or 'to conceal'. While 'celar' maintains the basic meaning of jealousy from its Latin root, 'recelar' has evolved to emphasize the suspicion and distrust that often accompanies jealousy. The 're-' prefix intensifies the original meaning.

The English word 'zealous' shares the same Latin root as 'recelar'. Both come from Latin 'zelari' (to be jealous), though they've evolved differently. While 'zealous' developed to mean 'passionate' or 'enthusiastic', 'recelar' took on the more negative connotation of suspicion and distrust that can come from excessive zeal or jealousy. Another related English word is 'jealous' itself, which also derives from the same Latin root.
