strict
estricta
describes an inequality in which the limit itself is not allowed; it uses < or >.
Example
"Less than 60" is strict: x < 60, so 60 is not allowed.
In Spanish
estricta — describe una desigualdad en la que el límite mismo no se permite; usa < o >.
"Menos de 60" es estricta: x < 60, así que 60 no se permite.
