The word 'dubious' means 'uncertain' or 'doubtful.' It is used when you are not sure about something or have doubts about it. For example, if someone offers you a job with very little information, you may feel dubious about whether it is a good opportunity. Or, if someone tells you a story that doesn't seem believable, you may feel dubious about its truthfulness. It can also be used to describe a person or their actions that seem suspicious or shady.
