The story you may have heardThe extracted draft put Arabic lawz 'almond' into the line, and the al- of almond looks like the Arabic article. Lawz is unrelated: it gave Medieval Latin amygdala only its anatomical sense 'tonsil' (a semantic loan). The al- is a Romance remodelling. Blažek has suggested a Semitic source for Greek amygdálē (compare Hebrew šāqēd 'almond'), but most specialists, following Beekes, treat it as Pre-Greek.
