• Synonym推し量るおしはかるNeutralA verb for inferring the unknown from what is known, at home in speech and writing; 「推察」 is a Sino-Japanese word with a more formal ring.
• Synonym推測すいそくNeutralThe most general, objective word for guessing, as in 「原因を推測する」; it lacks 「推察」's nuance of reading someone's feelings or situation.
• Synonym憶測おくそくWrittenWritten style for guessing on unreliable grounds, with a negative tinge, as in 「憶測が飛び交う」; 「推察」 is neutral and more considered.
• Synonym推量すいりょうWrittenWritten-style conjecture; also the grammar term in 「推量の助動詞」. 「推察」 more often suggests weighing matters or another's heart.
• Synonym推定すいていWrittenPresuming a fact from surrounding circumstances, as in 「推定年齢」; leans legal and statistical uses, unlike the broader 「推察」.
• Synonym推論すいろんWrittenLogical inference, mostly in academic argument, as in 「推論を重ねる」; 「推察」 is looser weighing, not step-by-step logic.
• Synonym忖度そんたくWrittenWritten word for reading another's mind; nowadays often implies pandering to a superior's wishes and carries a negative shade.
• Synonym推理すいりNeutralReasoning from facts or clues, with the weight on logic and detective work, as in 「推理小説」; 「推察」 is a looser, more considerate weighing.
• Synonym察するさっするNeutralA verb for sensing and showing consideration, as in 「お察しします」; centers on people's feelings rather than weighing facts.
• Synonym察しさっしNeutralA noun for the ability to read people and situations, as in 「察しがいい」.

• Synonym推知すいちWrittenWritten word for coming to know something by inference; rare, and leans toward the result of having figured it out.
• Synonym当て推量あてずいりょうCasualColloquial for guessing at random, as in 「当て推量で言う」; it is groundless, while 「推察」 rests on some basis.
• Synonym揣摩臆測しまおくそくWrittenA four-character idiom for wild conjecture with no grounds at all; strongly derogatory and far harsher than 「推察」.
• Synonym想察そうさつWrittenWritten word for imagining another's feelings or situation; rare.
• Synonym臆度おくたくWrittenWritten word for conjecturing without solid grounds; very rare.
• Synonym揣摩しまWrittenWritten word for conjecturing, mostly seen in 「揣摩臆測」; seldom used alone.

• Synonym推断すいだんWrittenWritten word for drawing a conclusion from given information; leans toward the conclusion reached.
• Related類推るいすいWrittenReasoning by analogy, as in 「類推が働く」; specifically draws conclusions from similarity, a narrower move than 「推察」.
• Related予測よそくNeutralPredicts future conditions — weather, trends, others' moves, as in 「予測がつかない」; 「推察」 is not limited to the future and often weighs the present and people's hearts.
• Antonym断定だんていNeutralDeclaring a firm conclusion; the opposite of 「推察」's tentative conjecture.
• Antonym確信かくしんNeutralFirm conviction without doubt; the opposite of 「推察」's tentative conjecture.

For plain, objective guessing say 「推測」. Use 「推察」 to weigh matters or another's feelings with a respectful tone, as in 「ご推察の通り」. For reading hearts, the verb is 「察する」; humbly 「拝察」 for your own surmise, 「ご賢察」 to ask the other's discernment. 「憶測」 is derogatory written style for baseless guessing, 「当て推量」 its colloquial counterpart. 「推定」 presumes facts, 「予測」 predicts the future, 「見当」 gives rough bearings, 「推理」 covers logic and detective work, 「忖度」 now often means pandering.
