What are other ways to spell fish?
The spelling of the noun and verb is "fish" (aquatic organisms). The other spelling to phish (phishing) is internet slang for attempting to illegal access personal information (usually by devious means).
Another spelling quirk that dates from 1855 is the semi-serious spelling of fish as "ghoti." This is meant to illustrate the confusing and conflicting pronunciations found in English. Ghoti uses the F sound of rough or tough, the I sound in women, and the SH sound of -tion words such as action.
