Expert writing Tips

Best practice

When using "fully know how", consider whether a more direct verb like "understand" or "comprehend" might be clearer and more concise. For example, instead of saying "I don't fully know how to operate this machine", you could say "I don't completely understand how to operate this machine yet".

Common error

Avoid using "fully know how" in formal or academic writing where a more sophisticated vocabulary is expected. Opt for terms like "thoroughly understand", "completely grasp", or "possess a comprehensive understanding" to enhance the formality and precision of your writing.
