as an adverb to strengthen it. Compare for example sentences such as I myself have never seen it.. The other cases can occur by themselves, but only in the singular, and are always used in combination with a possessive suffix that matches the subject of the sentence (i.e. always I see myself, never I see himself). These forms are irregular as well as suppletive: the illative and locative forms derive from completely different roots. There are also several alternative stems. Verbs Finite verbal categories The conjugation of Northern Sámi verbs resembles that of Finnish. There are three grammatical persons (persovnnat), and three grammatical numbers (logut), singular, dual and plural. There are four or five grammatical moods (vuogit): indicative (indikatiiva or duohtavuohki), indicating real events or statements of fact. imperative (imperatiiva or gohččunvuohki), indicating commands. optative (optatiiva or ávžžuhusvuohki), indicating wishes, things that the speaker would like to see done or realised. The optative is not usually considered a distinct mood, but is generally combined with the imperative. conditional (konditionála or eaktovuohki), indicating conditional or hypothetical statements, like the English subjunctive and the verb "would". potential (potientiála or veadjinvuohki), indicating ability or possibility. Tense is also distinguished, but only in the indicative. There are two tenses (tempusat): present (preseansa or dálá áigi), which is also used for future events (nonpast tense). past (preterihtta or vássán áigi). In addition, each mood and tense has a so-called connegative form. This form is used in negative sentences, when combined with the negative verb. Non-finite verbal categories Finally, there are several non-finite forms. Infinitive The infinitive is the dictionary form of the verb. Present participle The present participle is an adjective indicating a current or ongoing action. It is identical in form to the agent noun, and has the same origin. However, the participle has only an attributive form, no case forms. oađˈđi mánná – a sleeping child áhpásmeaddji buohcci – a recovering patient Past participle The past participle is an adjective indicating a past or completed action. Like the present participle, it has only an attributive form. It is also used in forming the periphrastic perfect tense, and as the connegative form of the past indicative. oađđán mánná – child who slept áhpásman buohcci – patient who recovered Agent participle The agent participle is an adjective indicating a past or completed action that has been completed by a particular agent. It only exists for
