Whether we are to say forecast or forecasted in the past tense & participle depends on whether we regard the verb or the noun as the original from which the other is formed; ... The verb is in fact recorded 150 years earlier than the noun, & we may therefore thankfully rid ourselves of the ugly forecasted; it may be hoped that we should do so even if history were against us, but this time it is kind. [Fowler, 1926]
关于过去时和分词形式是用forecast还是forecasted，取决于我们是把动词还是名词视为原始形式；……实际上，动词比名词早记录了150年，因此我们可以欣然摆脱那个难看的forecasted；即使历史对我们不利，但这次却是友好的。[Fowler, 1926]
