The term used for guessing depends heavily on whether you are making a logical inference, sensing an emotional state or speculating without evidence. 推測する is used for reaching an unconfirmed conclusion, often through logic or available information. The noun form, 推測, refers to the inference or conjecture itself.
What does it mean word for word?
The noun 推測 is composed of the characters 推, meaning to push or infer and 測, meaning to measure or estimate.
Which one should you use?
There are distinct nuances between the different ways to express guessing. 推測する refers to a logical or data-based guess. In contrast, 察する is used when you guess or sense someone's unspoken feelings, needs or a subtle social situation. 憶測する carries a more negative connotation, often implying that the guess is mere speculation or conjecture that lacks a factual basis.
