estanquéis

Estanquéis is not a standard verb form in contemporary Spanish. It is generally considered a misspelling or mistaken orthography for estanquéis, the correct second-person plural present subjunctive form of the verb estancar (to stall, to block, to stagnate).

The normative form for vosotros in the present subjunctive of estancar is estanquéis. This follows the orthographic rule for -car verbs in the present subjunctive, where the c changes to qu before the endings -éis to preserve the hard /k/ sound. The related forms are estanquemos (nosotros) and estanquen (ellos).

Usage notes and examples:

- Correct: Es importante que vosotros estanquéis el flujo de mercancías.

- Incorrect (commonly seen): Es importante que vosotros estanquéis el flujo de mercancías.

The latter is not recognized as standard in dictionaries such as the RAE, though occasional learners or writers may encounter it.

Etymology and related forms:

- Estancar comes from estancar-, with the present subjunctive endings applied to the stem. The spelling change from estancar to estanquéis is a regular adaptation for -car verbs in this mood, intended to keep the hard /k/ sound before the final -éis.
