Morphology
growth + regulator
The compound is a straightforward noun + noun combination where 'growth' specifies what is being regulated and 'regulator' denotes an agent or substance that controls something; therefore a learner who knows both words can infer 'something that regulates growth'. This compositional pattern (agent/substance that regulates X) is common across languages and follows regular English word-formation, so the meaning is immediately predictable.
Etymology
Growth regulator comes from the simple image of tiny helpers inside a plant that tell it how to grow. The word growth shows what they act on and regulator means they 'control' or change that growth, so the phrase now means a substance that makes a plant grow more, less, or differently.
