Grammaire

determiners

• Determiners help describe nouns, including countable (e.g., "apples") and uncountable nouns (e.g., "water").
• Countable nouns: Use numbers or words like "many" or "few" (e.g., "three books," "few opportunities").
• Uncountable nouns: Use words like "much," "some," or "little" (e.g., "much respect," "little time").
• Possessive determiners (e.g., "my," "your") work for both types.
• Articles like "a," "an," and "the" are also determiners, showing if something is specific or not.

Understanding these words makes communication clearer and more accurate.

adjectives

Adjectives describe things and feelings, and they change form to compare or show extremes:

• Regular Adjectives:
  • Add "er" for comparatives (e.g., "safer") and "est" for superlatives (e.g., "safest").
  • Use "more" and "most" for adjectives with two or more syllables (e.g., "more secure," "most secure").
• Irregular Adjectives: Change in unique ways:
  • Good → better, best
  • Bad → worse, worst
  • Far → farther/further, farthest/furthest
  • Little → less, least
  • Much/Many → more, most
• Special Cases:
  • Adjectives ending in "y" change to "ier" and "iest" (e.g., "happy," "happier," "happiest").
  • Use "than" with comparatives and "the" with superlatives (e.g., "faster than," "the fastest").

Comparatives and superlatives

help compare things or describe the highest degree of a quality:

• Comparatives: Compare two things (e.g., "bigger," "more productive"). Use "than" to connect them (e.g., "My desk is bigger than yours").

• Superlatives: Describe the highest degree (e.g., "biggest," "most productive"). Use "the" before the adjective (e.g., "This is the biggest desk").

How to Form Them:

One-syllable adjectives: Add "-er" for comparatives and "-est" for superlatives.

• Example: "fast → faster → fastest."

Ending in 'e': Add "-r" or "-st."

• Example: "large → larger → largest."

Ending in a consonant + vowel + consonant: Double the last consonant before adding "-er" or "-est."

• Example: "big → bigger → biggest."

Two or more syllables: Use "more" for comparatives and "most" for superlatives.

• Example: "beautiful → more beautiful → most beautiful."

Ending in 'y': Replace "y" with "ier" or "iest."

• Example: "happy → happier → happiest."

Irregular forms: Learn these by heart (e.g., "good → better → best").

passive /personal passive sentences 

The Impersonal Passive

structure is used for: Things that are thought, believed, said, or reported.

We form it like this: It + be + past participle of reporting verb + that + clause

Personal Passive sentences
