“línea dura” — hard or strict government policy

Borrowed from Latin līnea (“line, thread”), from līnum (“flax”), from Proto-Indo-European *līno- (“flax”). Compare the inherited Old Spanish form liña, still used in archaic modern Spanish. Cognate with Portuguese linha, Galician liña, and Catalan línia and llinya.
