regular sound change has made them the same form: these can be reanalysed as conversion. "Don't talk the talk if you can't walk the walk" is an example of a sentence using those forms. In other languages In other languages, verbification is a more regular process. However, such processes often do not qualify as conversion, as they involve changes in the form of the word. For example, in Esperanto, any word can be transformed into a verb, either by altering its ending to -i, or by applying suffixes such as -igi and -iĝi; and in Semitic languages, the process often involves changes of internal vowels, such as the Hebrew word "גגל" (, ), from the proper noun גוגל (). In Toki Pona, any content word may function as a noun, verb or adjective depending on syntax. For example, moku may either mean food or to eat. Noun conversion in English Many English nouns are formed from unmodified verbs: a fisherman's catch, to go for a walk, etc. Humor Verbification is sometimes used to create nonce words or joking words. Often, simple conversion is involved, as with formations like beer, as in beer me ("give me a beer") and eye, as in eye it ("look at it"). Sometimes, a verbified form can occur with a prepositional particle, e.g., sex as in sex it up ("make it sexier"). A Calvin and Hobbes strip dealt with this phenomenon, concluding with the statement that "Verbing weirds language", demonstrating the verbing of both verb and weird. (The former appears in its use as a gerund.) References External links "Grammar Puss" by Steven Pinker Figures of Speech "Verbing Nouns" Word coinage Linguistic morphology br:Verbadurezh
