tr.v. as·ter·isked, as·ter·isk·ing, as·ter·isks

[Middle English, from Late Latin asteriscus, from Greek asteriskos, diminutive of astēr, star; see ster- in Indo-European roots.]
Usage Note: The phonological phenomenon of metathesis involves the transposition of sounds or syllables in a word. Metathesis is responsible for the common rendering of ask as aks or ax. (This issue is discussed comprehensively at ax.) Similarly, one sometimes hears asterisk pronounced with the "sk" transposed to produce a (ks) sound, as though the word were spelled asterix or astericks. Then, perhaps because this symbol is often written as one of a series (as ***, for example), some people apparently infer that astericks is the plural of a singular asterick, pronounced with just a final (k) sound. In 2014, the Usage Panel overwhelmingly preferred the traditional pronunciation for asterisk, although 24 percent found the asterix pronunciation acceptable and 19 percent found asterick acceptable. A mere 7 percent personally preferred the asterix pronunciation, and only 6 percent preferred the asterick one. See Usage Note at ax2.
