See p. 319, No. II

(1) Except for the third pers. sing. and plur., the disjunctive pronoun is used for both genders indifferently, e.g. :

(a) c'est moi, maman, c'est Marianne: it is I, mother, Marian

(p. 167, Unes 8-9).

(b) c'est lui: it is ne; c'est elle: it is she.

(2) It is used after prépositions and conjunctions, e.g.:

(a) je voudrais savoir s'il y a des lettres pour moi: I would like to

know if there are any letters for me (p. 144, last para, second and third Unes).

(b) et vous, avez-vous fait bon voyage?: and you, did you have a

nice trip? (p. 96, fourth line up from bottom).

(3) Except for the third pers. sing. and plur., the disjunctive pronoun must replace the indirect object, direct object, and reflexive pronouns, in connection with an imperative affirmative, e.g.:

Dites-moi, qu'est-ce qu'il y a de nouveau à Fort William? (p. 129, last para, fourth line): tell me (indir. obj.), what is the news in Fort William?

The above rule applies only to the imperative affirmative; in the case of an imperative négative the disjunctive pronoun must not be used, e.g.:

affirmative: dites-moi; négative: ne me dites pas See p. 338, the imperative forms of a reflexive verb in the affirmative and négative.

(4) When preceded by à, in connection with the verb être, the disjunctive pronouns (and the interrogatives) dénote possession, e.g.:

(a) le livre est à moi (the book is mine) les livres sont à lui (the books are his)

(b) à qui est le chien? (whose dog is it?)
