Laziness is muckle worth, when it's weel guided.
Lazy youth maks lousy age.
Leal folk ne'er wanted gear.
Leal heart leed never.
"A' was toom, a' heartless-like, an' bare;
Her dowie pain she culdna mair conceal—
The heart, they'll say, will never lie that's leal."
—Ross's Helenore.
Lean on the brose ye got in the morning.
Spoken facetiously to a person who leans heavily on another.
Leap year was never a gude sheep year.
Learn the cat the road to the kirn, and she'll aye be lickin'.
