Thanks for the information and thoughts on this. I know how verbs can be changed into adjectives by using them in past participle form, e.g. the drunken man but in reference to birdeen's call I don't agree. With TheParser's example, wall to walled, it works but a verb from the noun eye doesn't make sense to me. The key aspect for me in most of the examples is that they are all compound adjectives, an adjective-noun form then being used as an adjective itself for another noun. They do look like verbs in there construction though, even the way the noun changes from a stand-alone noun to a noun being used in a compound adjective is very verb-like, consider, belly to bellied in 'pot-bellied pig', with the verbs, bully to bullied, hurry to hurried. I don't know how to explain the gemination of the g in 'three legs' to 'three-legged' from a verb point of view though, unless the s indicating plurality is altered into another g or if it is required for fluency because of the sounds involved. I don't know! Are there any verb forms that do this consonant gemination from present to past form?
