The Spanish word 'litis' comes directly from Latin 'litis', which was the genitive form of the Latin noun 'lis' meaning 'lawsuit' or 'dispute'. In Spanish, it retained its legal meaning and refers to a lawsuit or legal dispute. This is a formal or technical term primarily used in legal contexts.

'Litis' is a specialized legal term in Spanish, and there aren't many common Spanish words that share its etymology. However, you might encounter it in legal compound terms like 'litisconsorte' (co-litigant) or 'litispendencia' (pending litigation).

While there aren't many common English words directly related to 'litis', you might recognize it in legal English terms like 'litigious' (prone to engaging in lawsuits), 'litigation' (the process of taking legal action), and 'litigate' (to engage in legal proceedings). These words all share the same Latin root 'lis/litis' referring to legal disputes.
