For most Swedish strong verbs that have a verb cognate in English or German, that cognate is also strong. For example, "to bite" is a strong verb in all three languages as well as Dutch: {| class="wikitable" ! Language ! Infinitive ! Present ! Preterite/past ! Supine/perfect !

For verb groups 1–3 the supine is identical to the neuter form of the past participle. For verb group 4, the supine ends in -it while the past participle's neuter form ends in -et. Clear pan-Swedish rules for the distinction in use of the -et and -it verbal suffixes were codified with the first official Swedish Bible translation, completed 1541. This is best shown by example: Simple past: "I ate (the) dinner" – (using preterite) Composite past: "I have eaten (the) dinner" – (using supine) Past participle common: "(the) dinner is eaten" – (using past participle) Past participle neuter: "(the) apple is eaten" – Past participle plural: "(the) apples are eaten" – The supine form is used after ("to have"). In English this form is normally merged with the past participle, or the preterite, and this was formerly the case in Swedish, too (the choice of -it or -et being dialectal rather than grammatical); however, in modern Swedish, they are separate, since the distinction of -it being supine and -et being participial was standardised. Passive voice The passive voice in Swedish is formed in one of four ways: adding an -s to the infinitive form of the verb (s-passive); this form tends to focus on the action itself rather than the
