अनुमानसूचक मोडल क्रियाएँ: must, can't, might have
These modals let you reason aloud about something you're not certain of — deducing what must be true, what can't be true, and what might have happened — a job Hindi hands to होगा and its past-shifted forms.

Deduction about the present vs. deduction about the past
She must be tired. (present deduction) vs. She must have been tired. (past deduction, adding have + participle)
वह थकी हुई होगी। / वह थकी हुई रही होगी। (होगा से पहले रहा/रही जोड़ने से अनुमान भूतकाल की ओर खिसक जाता है)
Hindi marks epistemic deduction with होगा — literally the future form of होना, used here not for a real future but for present-tense probability: थकी हुई होगी, "she must be tired." To push that same deduction back into the past, Hindi inserts रहा/रही before होगा (थकी हुई रही होगी, "she must have been tired"), just as English inserts have + participle after the modal (must be → must have been). The same layering applies to can't (impossible) and might (uncertain): can't have left, might have forgotten. Words like शायद (perhaps) or ज़रूर (certainly) can be added on either side to fine-tune how confident the guess is, much like choosing must vs. might in English.
