Not clause for Twig templates

Question

How do I do a NOT clause in a Twig template similar to PHP's !? Given sick values of either true or false, I tried the following, but it throws an error.

{% if !sick %}
    Kenny is NOT sick.
{% elseif dead %}
    You killed Kenny! You bastard!!!
{% else %}
    Kenny looks okay --- so far
{% endif %}

"if not var"? Out on the run so couldnt check atm, strange if its not mentioned in the docs — JimL, Sep 22 '14 at 16:14
@JimL I was looking in the IF section http://twig.sensiolabs.org/doc/tags/if.html. Turned out to be located elsewhere. — user1032531, Sep 22 '14 at 16:26

You should use not keyword as negation.

{% if not sick %}
    Kenny is NOT sick.
{% elseif dead %}
    You killed Kenny! You bastard!!!
{% else %}
    Kenny looks okay --- so far
{% endif %}

Following this documentation page and this answear.
