l'utilisation du subjonctif

Question

Pouquoi ne pas utiliser " Savez que  vous êtes loin d'etre le seul au lieu de "Sachez que vous êtes loin d'être le seul"? L'utilisation du subjonctif est-elle nécessaire ?  Kevin

Accepted Answer

Kevin, this is not the subjunctive of savoir - it is the imperative, and is ‘irregular’ for savoir. 
The ‘vous’ conjugation of the subjunctive would be ‘sachiez’ but it is the imperative that is needed here, as the statement is in imperative form. 
The subjunctive is not needed with savoir in ‘positive’ statements either - only in the negative.
