young
The Vietnamese word "young" is not a Vietnamese term; in English, it refers to someone or something in an early stage of life or development.
The word 'trẻ' is an adjective describing someone's age implying youth.
Anh ấy rất trẻ, nhưng đã đạt được nhiều thành tựu.
He is very young, but he has already achieved much.
Here, 'trẻ' refers to the early stage of a tree's growth period.
Cây này còn trẻ nên cần chăm sóc tốt.
This tree is still young, so it needs good care.
In this context, 'trẻ' metaphorically describes the freshness and novelty of ideas.
