  • The current definitions and examples for indeclinable do not really help me to use or understand the word. I had to google it to find a better example.

    It seems relegated to grammatical jargon, since undeclinable better captures the description of things other than words that may not be declined.

    It seems that the grammarians and linguists have taken ownership of declinable and indeclinable. The definitions in Wordnik for declinable does not even capture the meaning that is given in the example. To correct this should be an undeclinable challenge.
