1. A palynodrome (from the Greek palin dromein, to go backwards) is a word, number or phrase that reads the same way forward as backward. If it is a number, it is called capicua
In linguistics, cognates are words that have a common etymological origin. In etymology, the cognate category excludes doublets and loan words. The word cognate derives from the Latin noun cognatus, which means "blood relative".
"ROSA"-"ROSE" is a word cognate in Spanish and English
False friends are words in two languages (or letters in two alphabets)[1] that look or sound similar, but differ significantly in meaning. An example is the English embarrassed and the Spanish embarazada (which means pregnant), or the word sensible, which means reasonable in English, but sensitive in French, German and Spanish.
"ADVICE" is a false friend, in Spanish is "consejo" and not "aviso"
REMEMBER: Not valid: conjugated verbs, proper nouns, derived words, plural or feminine
