I have been revising possessives over the break and noted the specific relatonships between possessives and nouns. It got me thinking about expressions where a possessive is used with a “verb” e.g. thanks for your help… obrigado pela sua/ tua ajuda etc…and on my train of thought went to, is it a verb in that context? or a noun (gerund) ? and how do the rules alter if at all, masc, feminine etc etc?
Any thoughts ?
