A teaspoon is an item of cutlery, a measuring instrument, of approximately 5ml, or a unit of measurement of volume (usually abbreviated tsp.).
A fifth is a unit of volume formerly used for distilled beverages in the United States, equal to one fifth of a US liquid gallon, 4⁄5 quart, or 25 3⁄5 US fluid ounces (757 ml); it has been superseded by the metric bottle size of 750 ml, sometimes called a metric fifth, which is the standard capacity of wine bottles world-wide and is approximately 1% smaller.
