Mnemonic
Think of 'SUPPOSED' as containing 'SUPPOSE' + 'D'. If you SUPPOSE something is true, it is only SUPPOSED to be true, not confirmed.
Conceptual Metaphor
SOCIAL RULES ARE PRESCRIPTIONS (You're supposed to queue.) | BELIEF IS A CONTAINER (The supposed facts were empty.)

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'be supposed to' literally as 'предполагается'. Use 'должен' for obligation ('I am supposed to go' -> 'Я должен пойти') or 'по слухам' for belief ('the supposed hero' -> 'так называемый герой').
- Confusing 'supposed' (adj.) with 'suppose' (verb) in sentence structure.
Common Mistakes
- Omitting the '-d' in 'supposed to' ('You're suppose to be here.' - INCORRECT).
- Using 'suppose to' instead of 'supposed to'.
- Mispronouncing it as /səˈpoʊz/ (like the verb) instead of /səˈpoʊzd/.

FAQ
Frequently Asked Questions
'Supposed to' often refers to an external rule, expectation, or plan ('The train is supposed to arrive at 9'). 'Should' more often implies a personal recommendation, moral duty, or what is advisable ('You should apologise'). They can overlap.
No, 'suppose to' is incorrect in standard English. The required form is 'supposed to' when indicating obligation or common belief. 'Suppose' is the base verb form ('I suppose you're right').
Yes, but context is key. In 'be supposed to' indicating a planned event ('The package is supposed to arrive tomorrow'), there is no inherent doubt, just stated expectation. As a pre-noun adjective ('the supposed villain'), it usually casts doubt.
It is pronounced as a /d/ sound (/səˈpoʊzd/). It is not silent. A common mistake is to say /səˈpoʊz/, which is the pronunciation of the verb 'suppose'.
