Matinal! (early bird)
This is the demonstrative adjective/pronoun for this (one), that (one), these (ones).
The only way to tell if you want it to be "THIS" vs. "THAT" is by adding -ci (this) or -là (that).
The demonstrative adjectives are: ce, cet, cette (this, that) and ces (these, those).
ce + masculine singular noun beginning with a consonant = ce moulin (this/that mill)
cet + masculine singular noun beginning with a vowel or silent h = cet appareil (this/that instrument) or cet hiver (this/that winter)
cette + feminine singular noun = cette revue (this/that magazine)
ces + all plural nouns = ces moulins (these/those mills) or ces revues (these/those magazines)
NOTE: The demonstrative adjective must be repeated before each noun.
ce lac et cette plage (that lake and beach)
ces aiguilles et ces épingles (these needles and pins)
If it is necessary to distinguish between "this" and "that" or between "these" and "those" -ci and là with hyphens are added to the nouns contrasted. To mean "this" or "those" add -ci; to mean "that" or "those" -là is added.
cette écriture-ci ou cette écriture-là (this handwriting or that handwriting)
ces poèmes-là et ces poèmes ci (those poems and these poems)
My students used to say "it's like saying this here and that there." Although I prefer not to say that, fine, if it helps you!
