  • The second object (COS) in French

    What is the second object complement in French ? 

    The second object complement (French: le complément d'objet second) is a complement that is preceded by a preposition. It completes the direct object complement in a sentence.

    To make it simple, the COI changes its name and becomes the second object complement: COS.


    COD COS Translations
    Pierre donne un cadeau à son frère Pierre donne un cadeau à son frère (Peter gives a gift to his brother)
    Julia achète un foulard à sa mère Julia achète un foulard à sa mère (Julia buys a scarf for her mom)

    How to recognize the COS in French ? 

    The COS indicates who benefits or who harms the action made by the subject.

    The complement is introduced by a preposition and is attached to a verb that is already built with a COD (after the latter, so it comes second)

    The presence of the COD is mandatory in this type of construction, otherwise the sentence will be incorrect.

    • Subject + verb + COD + COS


    Roméo annonce une bonne nouvelle à sa famille. (Romeo announce a good news to his family)

    • The subject is "Roméo"
    • The transitive verb is "annonce"
    • The direct object is "une bonne nouvelle"
    • "à sa famille" is a COI because you ask the question "à qui ?" 
    • But it is the second complement in the sentence, therefore it becomes a COS

    Papa a demandé une nouvelle voiture de service à son directeur général. (Dad asked a new service car to his CEO)

    • The subject is "papa"
    • The transitive verb is "a demandé"
    • The COD is "une nouvelle voiture de service"
    • "à son directeur" is a COI because you ask the question "à qui ?"
    • But it is a second complement in the sentence, therefore it becomes the COS

    The position of the COS in French 

    The COS can be placed in different ways in a sentence:

    • After the first COD
    • If the COS is a pronoun, it always stands before the verb.
    • If the COD and the COS are pronouns, we look at their grammatical person: in the 3rd person → the COD is before the COS; 1st and 2nd person => the COS is before the COD
    • If the verb is imperative, the COS is after the COD.


    Position COD COS Examples
    After the COD Papa a donné sa voiture Papa à donné sa voiture à maman (Dad gave his car to mom)
    Pronoun Papa a donné sa voiture à maman  Papa lui a donné sa voiture (Dad gave her his car)

    Papa l'a donné à maman

    La maîtresse prête un stylo à Marcel

    Papa la lui a donné 

    La maîtresse me le prête

    (Dad gave it to mom)

    (The teacher lends it to me)

    Imperative Donne lui ton sac Donnes-le lui (Give it to him)

    enlightenedIf the COS is usually placed after the COD, it sometimes happens to be placed before:

    • Le client a commandé au vendeur une voiture. (The client ordered to the seller a car)
    • Le client a commandé une voiture au vendeur. (The client ordered a car to the seller)

    ​The grammatical category of the COS in French

    As a general rule, the COS can not be deleted and it is part of the verbal group and a sentence can have two COS at the same time. 

    The grammatical nature of the COS can be: 

    • A noun 
    • A nominal group 
    • A pronoun


    Nature COS Translations
    Noun Selena emprunte un bijou à sa soeur (Selena borrows a jewel to her sister)
    Nominal group Pierre offre une montre au nouveau marié (Peter offers a watch to the new bride)
    Pronoun Marie lui donne un dilemme (Maria gaves him an ultimatum)
