Best practice

Always use the correct tense of the verb 'appear'. In most cases, the past simple 'appeared' is appropriate. For ongoing or recently completed actions, consider 'has appeared'.

Common error

Do not use the construction "is appeared" as it is grammatically incorrect. The past participle 'appeared' does not require the auxiliary verb 'is' in this context. Use 'appeared' instead.
