Definition: Hard to grasp; not obvious or easily understood; barely noticeable.

Alright class, settle down now, let’s talk about “subtle,” it’s true! The dictionary gives us a clue, a helpful word for me and you. “Hard to grasp” – like a tricky game, A little hidden, not quite the same. "Not obvious," that's key, you see, It doesn't shout out loudly for thee! Like a quiet whisper in a bustling hall, Or a shadow dancing, graceful and small. “Barely noticeable,” it’s true, it’s right, Something so gentle, shining with light – But not a blaze that grabs your eye, It slips past quickly, passing by. So “subtle” means something quiet and low, A feeling or change you might not know. It's about details, small and refined, A delicate beauty for the mind! Do you have any questions? Let’s discuss it with glee!
