what's the meaning of Allomorph, plz.
Please see my corrections to your post. We start sentences with a capital letter. It is also important to use full English words, not textspeak/netspeak - do not use "plz", use "please".
Also, it is faster for you to look up a word in the dictionary than to write a post here. You should ask us for help after you have looked up a word in the dictionary, if you do not understand the definition.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
needo, everybody should bookmark OneLook.com (click on the underlined link) for free access to many reliable dictiionaries.
Additionally, please note that a better title would have been 'allomorph'.
