| Common mistakes | Confusing with 'I can only expect' which implies certainty., Using 'speculate' as a noun instead of a verb., Omitting 'only' changes the meaning significantly. | Confused with 'imply' — remember, implying is saying something indirectly, while inferring is what the listener does., Using 'infer' without an object (e.g., saying 'I infer' without specifying what you infer from)., Assuming 'infer' and 'learn' mean the same thing. |
| Usage notes | Use this phrase when expressing uncertainty or making an educated guess. It's suitable for formal and informal contexts, but avoid it in casual conversations. | Use 'infer' when drawing conclusions from evidence or reasoning. It’s common in academic writing but less frequent in casual conversation where 'guess' might be used instead. |
