However, cache is a French word that has been anglicized with French spelling and pronunciation. In addition, some English words do not conform to the “e makes the vowel say its name” rule. For example, “have.”

When a syllable ends in a consonant and has only one vowel, that vowel is short. Examples: “fat, bed, fish, spot, luck”.

When a syllable ends in a silent “e”, the silent “e” is a signal that the vowel in front of it is long. Examples: “make, gene, kite, rope, use, taste, and baste”.

So it should be pronounced Kaysh

usage In forte we have a word derived from French that in its “strong point” sense has no entirely satisfactory pronunciation. Usage writers have denigrated \ˈfȯr-ˌtā\ and \ˈfȯr-tē\ because they reflect the influence of the Italian-derived 2forte. Their recommended pronunciation \ˈfȯrt\, however, does not exactly reflect French either: the French would write the word le fort and would rhyme it with English for. So you can take your choice, knowing that someone somewhere will dislike whichever variant you choose. All are standard, however. In British English \ˈfȯ-ˌtā\ and \ˈfȯt\ predominate; \ˈfȯr-ˌtā\ and \fȯr-ˈtā\ are probably the most frequent pronunciations in American English.

I am reminded of an awful sign at a local mall declaring that the place is a “shopping centre” with an accent over the last “e.” The practice says more about putting on airs by trying (in a mangled way) to sound European than it does about honoring one’s native language.
