"My right shoe is gone!"

'My right shoe is lost' would be more appropriate in that case.

Gone is not a dutch word

We don't really use 'rechter' and 'linker' as adjectives. In Dutch, they are part of the noun.

• Rechterschoen
• Linkerhand

However, this is not always the case. It only happens with body parts, clothing, sports, 'buildings' (e.g. 'linkerdeur' (left door)), vehicles and figures. In other cases, they are separate words So it's:

• Linker stoel
• Rechter buurman
