どうも

What it means

どうも (doumo) is a compact, highly flexible Japanese interjection and adverb that serves as a short, context-dependent conversational signal to acknowledge someone, add emphasis, or express a vague attitude without detailed phrasing.

Main meanings

• 1. A concise expression of gratitude used alone or before a bow, functioning as an informal 'thanks'.
• 2. An intensifier meaning 'very' or 'extremely' when placed before adjectives or adverbs.
• 3. A softening marker in apologies or regrets, adding politeness without a long explanation.
• 4. A filler indicating vagueness or uncertainty equivalent to 'somehow' or 'for some reason'.
• 5. A casual greeting or attention-getter in passing interactions, similar to 'hi' or 'cheers' in some contexts.

How to use it

Common in casual and semi-formal speech, used alone as a short thank-you in shops or between acquaintances, prefixed to adjectives for emphasis in spoken sentences, inserted in apologies to soften tone, and deployed as a quick greeting or attention-getter in passing; register depends on intonation and additional words (it is less common as a standalone full-form phrase in very formal contexts).
