61In that connection, the Court has had the opportunity to state that the requirement of transparency of contractual terms, also repeated in Article 5 thereof, cannot be reduced merely to their being formally and grammatically intelligible, but that, to the contrary, since the system of protection introduced by Directive 93/13 is based on the idea that the consumer is in a position of weakness vis-à-vis the seller or supplier, in particular as regards his level of knowledge, that requirement of plain and intelligible drafting of contractual terms and, therefore, the requirement of transparency laid down by the directive must be understood in a broad sense (judgment of 20 September 2017, Andriciuc and Others, C‑186/16, EU:C:2017:703, paragraph 44 and the case-law cited).
