How do I write a lexicon for the following words: sand goanna, dog, mosquito, spear, child, man, stone, prickle, and rabbit?

How would I write rules describing the allomorphic variations in the forms of any of the morphemes?

Lexicons are dictionaries, of sorts. For each of these words, list all its definitions.

I am not familiar enough with the words in the second question to help. Sorry.
Does it matter what kind of dictionary (such as pocket size, trial size, or regular standard) when it comes to dictionaries? Is it alright to use a thesaurus? What type of dictionaries are you talking about like Legal, Business, Law, etc? How many definitions are recommended to be used when writing a lexicon?
