Diction

While proper tools will help complete a good job, good diction forms the basis of a clear message.

Below are two sentences taken from an Advertorial of a popular national English daily:-

(A) So if you or a loved one wear dentures, here are some useful tips.
(B) If you have eaten or drunk hot foods and beverages, it may need to be reapplied.

Sentence (A) is ignoring proximity principle and should have been - So if you or a loved one wears dentures, here are some useful tips.

Sentence (B) has an awkward arrangement of words which should have been rearranged to appear: If you have eaten hot foods or drunk hot beverages, it may need to be reapplied. However, if you use a common action verb like 'take' or 'consume' (while noting that the phrase 'hot foods and beverages' does not necessarily mean 'hot foods and hot beverages'), the sentence can be less clumsy as 'If you have taken hot foods or hot beverages, it may need to be reapplied.'

First, learn the meaning of what you say, and then speak.
