While preparing for IELTS Academic, I was practicing Writing Task 1.
In the task it is said:
Below is a map of the city of Brandfield. ...
Commonly, the first sentence of an essay should rephrase the task, so I came up with:
The map presents a sketchy scheme of ...
By sketchy I mean something that contains few details, as according to Cambridge definition.
But I'm afraid that sketchy is not the appropriate word for the formal writing, and I am certainly sure that IELTS Academic essays should be formal.
Research before asking:
1. Google responds to "sketchy meaning" with 2 slang dictionaries out of 3 top results.
2. In 4 out of 5 first not slang dictionaries that Google gave (Merriam-Webster, Dictionary.com, Cambridge, The free dictionary, Macmillan) the word sketchy has an informal meaning among others. 3. However, in SkELL there are 126 entries of sketchy in British National Corpus.
The question: Is this appropriate to use sketchy in this case?
