The superlative adjective is that form which expresses the greatest increase or diminution of
the quality: nicest. An adjective is in the superlative form when it expresses a comparison
between one and a number of individuals taken separately
RULES FOR SUPERLATIVE ADJECTIVES
Rule 1: When an adjective consists of one syllable add est to the end to make it a superlative
Exception to Rule 1: If the one syllable adjective ends with a consonant-vowel-consonant we
need to double the last consonant before adding the est. However, if the last consonant is a w
then we follow rule 1 instead.
Rule 2: When a two syllable adjective ends with y we need to replace the y with an i and then
add the est.
Rule 3: For an adjective with two or more syllabus (that does not end with y), we use add the
word most or least in front of the adjective.

How + Adjectives
Another use of "How long..." (How + Adjectives)
How wide - How deep - How long
"How long" is also used with the verbs "is" and "are" to know the length of something. Look at
Example: How long is the pipeline?
Other adjectives used with "How":
How wide is the bed? = What is the width of the bed?
How deep is the well? = What is the depth of well?
How big...? = What is the size of...?
How tall...? = What is the height of...?
How far...? = What is the distance...?
How high...? = What is the height of...?
How do we measure length? In the USA, we still use inches, feet, yards, and miles:
1 inch = 2.54 cm
1 foot = 30.48 cm
1 yard = 914 cm
1 mile = 1.6 km
Asking questions, example: Wide:
The bed is 64 inches wide.
What is the height of Angel?
Height is 6 feet 11 inches
Note: When we speak about objects, buildings, for example, we can ask "How high is it?", but
it is not possible to ask "how high" a person is when speaking about dimensions. We use a a
different adjective beginning with a "t"!
