mal- 複合詞
 不好,不良,惡劣


 Mal- A prefix in composition denoting ill, or evil, F. male, adv., fr. malus, bad, ill.  In some words it has the form male-, as in malediction, malevolent. See Malice.
 Note: ☞ The form male- is chiefly used in cases where the e, either alone or with other letters, is pronounced as a separate syllable, as in malediction, malefactor, maleficent, etc. Where this is not the case, as in malfeasance or male-feasance, malformation or male-formation, etc., as also where the word to which it is prefixed commences with a vowel, as in maladministration, etc., the form mal is to be preferred, and is the one commonly employed.
