How to use 无疑
无疑 is a fairly formal word used in writing, news, and speeches to state a strong conclusion. It often comes before a verb or before 是. Example: 这无疑是最好的办法。(Zhè wúyí shì zuì hǎo de bànfǎ.) This is undoubtedly the best way.
无 (wú) means "without" and 疑 (yí) means "doubt," as in 怀疑 (huáiyí). Put them together and you get "without doubt," so 无疑 simply means undoubtedly.
Common mistake: Learners sometimes mix up 无疑 (undoubtedly) with 怀疑 (huáiyí, to doubt), which has nearly the opposite meaning even though both contain 疑. Also keep the second syllable in the second tone, yí, not yì.
