Definition / Explanation
At advanced level, speakers often express probability and attitude through larger patterns, not only simple modal verbs. English uses bundles such as be bound to, be likely to, be unlikely to, apparently, presumably, and seem to to show how certain or uncertain the speaker feels. These expressions help us manage stance, meaning our degree of confidence, caution, or distance from a claim. They are especially common in discussion, analysis, and formal argument. Choosing one pattern over another often changes the tone from confident to careful.
Key Rules
- Use be likely to / be unlikely to for reasoned probability.
- Use be bound to for strong expectation, often based on logic or experience.
- Use adverbs such as apparently, presumably, and evidently to comment on the source or strength of information.
- Use seem to / appear to when you want to sound cautious or observational.
- These patterns often express stance more precisely than a simple may or might.
Examples
- She's bound to notice.
- It's likely to take hours.
- He appears to know more than he says.
- Apparently, the meeting was cancelled.
- They are unlikely to accept the offer.
Common Mistakes
- ❌ She is bound noticing. -> ✅ She is bound to notice.
- ❌ It is likely that takes hours. -> ✅ It is likely to take hours.
- ❌ Apparently he is seems tired. -> ✅ Apparently he seems tired.
