Constructed-language mapping: given migenlasan = cupboard, lasanpoen = boardwalk, cuopdansa = pullman, determine which option encodes 'walkway' by isolating the morpheme for 'walk'

Given data

• migenlasan = cupboard.
• lasanpoen = boardwalk.
• cuopdansa = pullman.
• Goal: 'walkway'.

Concept/Approach (why this method)

Find common segments: lasan appears in cupboard and boardwalk, naturally mapping to 'board'. Then infer the remaining part in boardwalk (poen) as 'walk'. Combine 'walk' with a plausible morpheme for 'way'.

Step-by-Step decoding
1) From lasanpoen (boardwalk), map lasan = board.2) Therefore, poen = walk.3) A reasonable encoding for 'way' in options is forc (unused elsewhere and placed as a head or suffix).4) Compose 'walkway' as poen + forc ⇒ poenforc.

Verification/Alternative

Check patterns: Compounds are formed by direct concatenation. poenmigen would mean walk+cup, not 'walkway'; lasandansa mixes board with an unrelated morpheme.

Common pitfalls

• Assuming 'lasan' means walk (it appears in cupboard, contradicting that).

Final Answer
poenforc
