In some languages, the formal representation of aspect is optional, and can be omitted when the aspect is clear from context or does not need to be emphasized. This is the case, for example, in Mandarin Chinese, with the perfective suffix le and (especially) the imperfective zhe. For some verbs in some languages, the difference between perfective and imperfective conveys an additional meaning difference; in such cases, the two aspects are typically translated using separate verbs in English.
