Convergent, compatible, contradictory: compare French source relationships
Compare five explicitly different relationships between French source statements, from convergence to contradiction, while treating silence as lack of evidence.

In short
Convergence shares a claim; compatibility allows claims to coexist; contradiction makes them incompatible in the same scope. Tension may disappear once an exception or difference in scope is explained. A source’s silence about an issue is not its agreement with another source.

Source A · phrase fixe pour les cinq comparaisons
La bibliothèque sera ouverte ce samedi de 9 h à 12 h.
Incompatible same-scope claim
- B indique : « Ce même samedi, la bibliothèque sera fermée toute la matinée. »B states that on that same Saturday the library will be closed all morning.Contradiction: same venue, date and period, with incompatible opening claims.
- B indique que la bibliothèque est habituellement fermée le samedi matin.B states that the library is usually closed on Saturday mornings.Tension: a general usual pattern sits uneasily with A’s specific announced opening, which could be an exception.
- B décrit l’accès par une rampe, sans donner d’horaire.B describes ramp access without giving opening hours.Compatibility on different dimensions: both claims can hold, but B gives no confirmation of A’s hours.
- B indique : « Il sera possible de venir samedi entre 10 h et 11 h. »B states that visiting will be possible Saturday between ten and eleven.Partial overlap: this interval fits inside A’s announced opening, without confirming every hour.
- B indique aussi : « La bibliothèque sera ouverte samedi de 9 h à 12 h. »B also states that the library will open Saturday from nine to noon.Convergence: the same opening claim is explicitly made.
Same claim
Compare the relation, not the truth score
The sequence moves from explicit agreement toward direct conflict in this particular set of examples. It does not assign certainty percentages or rank every use of these adjectives universally. Compatibility is weaker than confirmation here because ramp access says nothing about opening times.
A contradiction needs a shared reference
Ce même samedi and toute la matinée make the final conflict precise. A different Saturday, a separate building or a different service could remove it. The fourth step says habituellement, so an exceptional opening remains possible. That makes it tension rather than an unavoidable contradiction.
Les horaires annoncés paraissent en tension avec la règle habituelle ; il faut vérifier s’il s’agit d’une ouverture exceptionnelle.
The announced hours seem in tension with the usual rule; it is necessary to check whether this is an exceptional opening.
Before choosing a relationship word, state exactly which proposition you are comparing. Then check time, place, population and qualification. The label should summarise that comparison rather than replace it.
