Describing something that is full of flowers or in the process of flowering.
The garden was abloom with vibrant flowers in the spring.
Abloom is formed from the prefix "a-" (meaning in the state of) and the root "bloom" (from Old English "blōma", meaning flower or blossom). The word "abloom" describes something that is in the state of blooming or flowering.
Imagine something that is 'in the state of' blooming — that's what 'abloom' means.
