After the modal verbs ought to, should, could and verbs expressing hope or intention the perfect form denotes an action that was not fulfilled. e.g. You could have helped them (but you didn't). I intended to have helped them (but I didn't). With the modal verbs must, may (might) the perfect form of the infinitive expresses probability with regard to prior action. e.g. She must have forgotten to ring them up (Она долясно быть забыла позвонить им). She may have forgotten to ring them up (Возможно, она забьша позвонить им). The English Infinitive exists in two presentation forms. One of them, characteristic of the fi:ee uses of the Infinitive, is distinguished by the prepositional marker to. This form is called traditionally the 'to-infinitive'. The other form, characteristic of the bound uses of the Infinitive, doesn't employ tlie marker to; this form is called traditionally 'the bare infinitive'. The infinitive marker 'to' is a word-morpheme, its only function is to build up and identify the infinitive form as such. e.g. You are welcome to acquaint yourself witla any of the documents if you want to. Like other analytical markers, it can also be separated fi-om infinitive part by a word of phrase, usually of adverbial nature, forming the so-called 'split infinitive'. 19
