Covered by trees or bushes; wooded.
Late 16th century from Middle English bosk, variant of bush.
A swale is swell
If it’s tended well,
But nature does its best,
Well beyond our behest
To block the sun to merely dapling
With bosky bits of shrub and sapling.
You might wish to grump and grouse
As you wander, aimless, through your house.
I’ll attempt to reassure a bit
You’ll need not have a literate fit.
I tried to avoid well known “bosky Dell”
And, of course, swell HP just as well.
