When writing an administrative letter, you reread a phrase like “the persons entitled to this benefit” and doubt arises: should you write “aillant” or “ayant”? The confusion almost always comes from spoken language, where rapid pronunciation blurs the distinctions.
“Ayant” is the only correct form of the present participle of the verb avoir. “Aillant,” on the other hand, is related to the verb “aller” conjugated in the present subjunctive (que nous aillions, qu’ils aillent) and has nothing to do with possession.

When spoken language creates mistakes with forms ending in -ant
Most errors do not stem from a lack of knowledge of grammar. They arise from a phonetic reflex. In spoken language, the difference between “ayant” and a hypothetical “aillant” is rarely heard. The brain associates the sound with a plausible spelling, and the mistake settles in before one even opens a dictionary.
This phenomenon affects other forms ending in -ant. One hesitates between “fatigant” and “fatiguant,” between “provoquant” and “provocant.” The mechanism is the same: the ear catches a sound, the hand transcribes an approximation. To learn everything about aillant or ayant, it’s quicker to start from the source verb rather than the heard sound.

The present participle in French is constructed from the radical of the verb in the first person plural of the present indicative, to which -ant is added. “Avoir” gives “nous avons,” thus “ayant.” Not “aillant.” This mechanical rule works for the vast majority of verbs and constitutes the quickest test.
Present participle, verbal adjective, and gerund: three traps in one
Understanding why “ayant” poses a problem also involves untangling three grammatical categories that are often confused in writing.
The present participle remains invariable
The present participle does not take gender or number markers. One writes “the children having completed their exercise” without ever agreeing “ayant.” This rule is strict, regardless of the context.
The verbal adjective agrees
When a form ending in -ant functions as an adjective (it qualifies a noun and can be replaced by another adjective), it agrees. One writes “a helpful person,” “convincing arguments.” The verbal adjective agrees in gender and number with the noun it qualifies, unlike the present participle.
The concrete trap: “ayant” never transforms into a verbal adjective. One would not say “a person ayante droit” (even if the expression “ayant droit” can take a plural: “les ayants droit”). This peculiarity explains part of the hesitations.
The gerund with “en”
The gerund is constructed with “en” followed by the present participle and always remains invariable. “En ayant knowledge of the file, she was able to respond.” Here, “en ayant” forms a fixed block. There is no reason to write “en aillant,” which does not exist in this construction.
- Present participle: invariable, expresses a simultaneous action or a cause (“Persons having a valid title can enter”).
- Verbal adjective: variable, qualifies a noun like a classic adjective (“a provoking remark”). “Ayant” does not fall into this category.
- Gerund: “en + present participle,” invariable, indicates manner or simultaneity (“by having prepared their documents”).
Ayant: a form mostly present in structured writing
One encounters “ayant” much more often in writing than in speech. Administrative, legal, and professional texts are full of it: “persons having submitted a file,” “any employee having acquired their rights,” “the company having signed the contract.” In everyday conversation, one almost always rephrases differently.
It is precisely this gap between written and spoken usage that fuels the confusion. One rarely hears “ayant” in a discussion, but it must be written in formal situations where the error is immediately noticeable. A CV, a complaint letter, a notarial act: the mistake “aillant” in these contexts gives a poor impression of language mastery.
Professional instructions, news articles, and academic writings massively use the present participle to condense information. “Victims having suffered harm” is more compact than “the victims who have suffered harm.” This syntactic density explains its frequency in formal registers.
Concrete method to no longer confuse aillant and ayant
Rather than an abstract rule, one can apply a two-step test whenever doubt arises.
First step: identify the source verb. If the sentence talks about possession, a state, or a condition (“to have the right,” “to have finished,” “to have knowledge”), the verb is “avoir.” The present participle of avoir is “ayant.” End of debate.
Second step: if the sentence talks about movement or direction, the verb is “aller.” In this case, the form “aillant” does not exist either as a present participle. The present participle of aller is “allant.” The form “aillant” is only correct in the present subjunctive of the verb aller (“it is necessary that we go there”), and it is never used alone as a participle.
- “The children having hunger ate early” – verb avoir, present participle “ayant,” invariable.
- “It is necessary that we go to the office” – verb aller, present subjunctive, no relation to “ayant.”
- “By having prepared the file, we avoid delays” – gerund with avoir, always “ayant.”
If one can replace the doubtful form with “possessing” or “holding” and the sentence retains its meaning, it is indeed “ayant” that should be written. This substitution test works in the vast majority of situations.
The confusion between “aillant” and “ayant” disappears as soon as one returns to the original verb. Identifying the source verb resolves the question in a few seconds. The habit of this reflex makes the verification automatic, even in the face of long sentences or complex administrative constructions.
