From Idylls of the King: The Passing of Arthur by Alfred Tennyson:
To him replied the bold Sir Bedivere:
'It is not meet, Sir King, to leave thee thus,
Aidless, alone, and smitten through the helm—
A little thing may harm a wounded man;
Yet I thy hest will all perform at full,
Watch what I see, and lightly bring thee word.'
What does "it is not meet" mean in the context of leaving someone ill?
