Vague words are those that can have an ambiguous or unknown meaning when used without clarification. Try to use these as little as possible.
For example, what does the word 'clean' mean in respect of, say, a vehicle? Does it mean -
- just washed and polished? or
- there's no rust on it? or
- there’s a full service history available, or
- it hasn't been in any accidents, had panels replaced etc
Other words/phrases to avoid are:
By whose standards? - you may want equipment that can work flat out 24-7 whereas someone else may consider 10% down time acceptable.
'As Soon As Possible'
In respect of delivery - do you mean you want it very quickly or as soon as the supplier can deliver?
