Yes, in the phrase ‘because there’s no room,’ there is a contractible copula. To understand this, we need to break down what a copula is. A copula is a word that links the subject of a sentence with a subject complement; in English, the most common copula is the verb ‘to be.’
In this case, ‘there’s’ is a contraction of ‘there is,’ where ‘is’ acts as the copula. The phrase essentially states that ‘there is no room,’ where ‘is’ connects ‘there’ with ‘no room,’ indicating the existence of space—or, in this instance, its absence. Contractible copulas occur in English when ‘is’ or ‘are’ can be expressed in a contracted form (e.g., ‘there’s’ for ‘there is’).
Thus, the use of ‘there’s’ showcases the contractible nature of the copula in informal speech and writing, making it a common and natural part of English communication.
