The hesitation between “blocant” and “bloquant” often arises in professional exchanges, meeting minutes, and IT support tickets. Only the form “bloquant” is correct in French, with a “qu” inherited from the verb “bloquer”. The spelling “blocant” does not exist in any reference dictionary, but it persists in quick written usages, probably by analogy with the noun “bloc”.
Bloquant or blocant: comparative table of forms
| Criterion | Bloquant | Blocant |
|---|---|---|
| Presence in the Larousse dictionary | Yes | No |

The confusion arises from the fact that both pronunciations are identical. In writing, however, the difference is clear: “bloquer” retains its “qu” in all its conjugated forms, including the present participle.

Why “bloquer” retains its “qu” in the present participle
In French, verbs ending in -quer follow a regular conjugation logic. The root of “bloquer” is “bloqu-“, and the present participle is formed by adding “-ant” to this root. This gives “bloquant”, without exception.

The temptation to write “blocant” comes from a confusion with the noun “bloc”, which belongs to the same etymological family but does not share the same morphological construction. The noun “bloc” does not generate a direct verbal form: it is “bloquer” that plays this role.
Other verbs ending in -quer follow exactly the same pattern:
- “Provoquer” gives “provoquant” (not “provocant”, which is a distinct adjective with a different meaning)
- “Communiquer” gives “communiquant” in the present participle, not to be confused with “communicant” (adjective and noun)
- “Fabriquer” gives “fabriquant” in the present participle, while “fabricant” is the noun that designates a person or a company
This last series shows a precise grammatical phenomenon. Some verbs ending in -quer have a derived adjective or noun in -cant, spelled differently from the present participle. “Bloquer” is not one of those cases with dual forms: there is no adjective “blocant” recognized by grammars.
Blocking incident in IT and project management
The word “bloquant” has taken on considerable importance in professional vocabulary, far beyond its basic grammatical meaning. In ticketing systems like Jira or ServiceNow, the classification of anomalies is based on three levels of severity: blocking, major, and minor.
An incident classified as “bloquant” completely prevents the use or deployment of a service. A “major” incident causes significant disruption without causing a complete halt. This distinction has direct contractual consequences in specifications and service level commitments.
In sprint meetings or project reviews, the phrase “is it blocking?” is used to sort priorities. The answer determines whether a team interrupts its ongoing work to resolve the issue or addresses it in the next cycle.
Writing correctly in a technical context
Spelling mistakes in a support ticket or technical report rarely go unnoticed. Writing “bug blocant” in a report intended for a client or a steering committee undermines the credibility of the document. The correct form remains “bug bloquant”, “blocking point”, “blocking anomaly”.
In the feminine form, “bloquant” becomes “bloquante” and in the plural “bloquants” or “bloquantes”. The “qu” is maintained in all inflections.
Beta-blockers in medicine: a common usage of the term
The medical field has popularized the word “bloquant” through beta-blockers, a class of medications prescribed to treat high blood pressure, certain heart rhythm disorders, and heart failure. These medications work by blocking beta-adrenergic receptors, hence their name.
Propranolol is among the most well-known beta-blockers. This therapeutic class is prescribed by the doctor according to the patient’s profile, the dose, and the expected effects on the heart and cardiovascular system.
The same logic of formation is found in “alphabloquant”, which targets alpha receptors. In both cases, the spelling follows the rule of the verb “bloquer”: the “qu” is always present. Patients seeking information about their treatment sometimes encounter the incorrect spelling “bêta-blocant” in forums or unedited articles, which can create unnecessary confusion.
Quick method to stop hesitating between blocant and bloquant
The most reliable check comes down to one question: does the word come from the verb “bloquer”? If yes, the “qu” remains. This logic works for all forms: bloquant, bloquante, bloquants, bloquantes.
- Test the substitution: replace with “which blocks” in the sentence. If the meaning is preserved, the correct form is “bloquant” (with “qu”)
- Remember that “bloc” and “bloquer” share a root, but do not have identical spelling in all forms
- Use a spell checker set to French: the form “blocant” will be systematically flagged as an error
The spelling “blocant” does not appear in Larousse, Robert, or Wiktionary. Its total absence from reference dictionaries makes it an unambiguous mistake, unlike other spelling hesitations where two forms coexist with distinct meanings.
