I lift the bloom but am not the crown, I carry life from root to gown. Cut me short and words begin, Add me to study careers win. What am I?

Leaf broth, Hot or cold, Spill me? Secrets unfold

Three: top family guy, get something on Three more: lock lover, pitch to a song Jack or Jenny, known as headstrong

When the clock's hands greet at day's closure, a glass clinks with laughter; joy flows like liquid gold, a brief escape from the tick-tock's grip.

I'm light and airy, yet I hold my shape, A cushion for comfort, or a wave's playful escape, In a cup of coffee, I'm a tasty delight, In a mattress, I'm the key to a peaceful night.
