Is there an English word for a fear of salt?
Solution 1:
halophobia, from the Greek ἅλς, ἁλός. cf. halomorphic, halophytic. See also O.E.D. halo-, comb. form, according to which the pronunciation is: /hæləʊ-/.
If I am not mistaken, the word denoting fear of x = the Gr. root of x + o + phobia.
natrophobia is not correct, as the Gr. word is νίτρον, giving nitrophobia. But νίτρον is sodium carbonite, not s. chloride.
