Expressing Speculation & Probability

A graded scale: devoir for confident inference, futur for present guesses, il se peut que for weak possibility

French grades certainty across three different tools rather than one word: devoir + infinitif states a confident inference (il doit être fatigué, 'he must be tired', based on evidence), the futur simple can speculate about the present itself (il sera 15h, 'it's probably 3pm' — a genuinely French-specific use of a 'future' tense for a present guess, sometimes called the futur de conjecture), and il se peut que + subjonctif marks weaker, open possibility. Malayalam reaches similar shades of certainty through suffixes rather than separate grammatical tools: -ആയിരിക്കണം leans toward confident inference (ക്ഷീണിച്ചിരിക്കണം, 'must be tired'), -ആയിരിക്കും guesses at a present fact (മൂന്ന് മണിയായിരിക്കും, 'it's probably three'), and -ഏക്കാം marks weaker possibility (പെയ്‌തേക്കാം, 'might rain') — pay attention to which French tool matches the exact suffix you'd reach for in Malayalam.
