Spinto (from Italian, "pushed") is a vocal term used to characterize a soprano or tenor voice of a weight between lyric and dramatic that is capable of handling large musical climaxes in opera at moderate intervals. (Sometimes the terms "lirico-spinto " or "jugendlich-dramatisch " are used to denote this category of voice.)
Spinto could mean another thing other than a soprano or tenor voice of a weight between lyric and dramatic that is capable of handling large musical climaxes in opera at moderate intervals.
We can't be so sure that Spinto is reserved for that term. Spinto in another sense could be the name of a food, animal, place or thing.
