Can a physical quantity have direction and still be a scalar?

Yes, a physical quantity can have magnitude and direction but still be a scalar if it doesn't obey the vector addition. An example is Electric Current which has magnitude and a fixed direction, but it does not follow vector laws of addition.

The Moon

Silent and still, the moon shines bright
In the dark, clear sky
Peaceful and calm, the night
A soothing balm to the weary eye

The moon, a glowing orb of light
Illuminates the path ahead
As the night wind whispers through the trees
And the stars twinkle overhead

So let us lay down and rest
And let the moon and night provide
The peacefulness and solitude
That we all need to feel alive
