The lightsaber, sometimes referred to as a laser sword, is a weapon used by the Jedi, the Sith, and other Force-sensitives. Lightsabers consist of a plasma blade, powered by a kyber crystal, that is emitted from a usually metal hilt and can be shut off at will.
An article (abbreviated ART) is a word (or prefix or suffix) that is used with a noun to indicate the type of reference being made by the noun.
The definite article is expressed, as in Hebrew, by h prefixed. Note the use of the definite article instead of a personal pronoun. The definite article the had been used in each case with a singular noun. It is said that the definite article usually at this time designates 'the College of Physicians'. There is a reason for the definite article, as we have found elsewhere.
