✕Common Mistakes
C'est un bon sac à dos aussi.
Placing aussi after the noun can change emphasis; the natural order is C'est aussi un bon sac à dos.
Il est aussi un bon sac à dos.
Do not replace C'est with Il est when identifying a noun; Il est is used for adjectives only.
C'est aussi une bon sac à dos.
Using the feminine article ‘une’ would be incorrect because sac à dos is masculine.

Cultural Tip
In French, C'est is preferred over Il est when you are identifying something (C'est un sac) rather than describing a known subject (Il est bon). The adverb aussi usually comes right after the verb or before the adjective, as in this sentence. Note that sac à dos is a masculine noun, so the article and adjective stay in the masculine form. French speakers often add a personal touch by mentioning the material or durability (e.g., un sac à dos solide).
