"A substitution table is built on a given sentence pattern. It consists of several text columns, each one of which is formed by words that can play the same role within the sentence. The student should go through all the possible combinations to get acquainted with the idiosyncrasies of each item:
The happy broom takes the animals
A(n) black footstep cleans a(n) postcard
My pregnant neighbor breaks my speaker
Your gorgeous lollipop throws your book
Our heavy bird makes our apple-pie"
Strange, eh? But I suppose you could make the same kind of table with comparative and superlative adjectives and adverbs.
