Future active participle of cōgō.

coāctūrus (feminine coāctūra, neuter coāctūrum); first/second-declension participle

1. about to compel, force or encourage
   • c. 52 BCE, Julius Caesar, Commentarii de Bello Gallico 1.6:

     Allobrogibus sēsē vel persuāsūrōs, quod nōndum bonō animō in populum Rōmānum vidērentur, exīstimābant, vel vī coāctūrōs ut per suōs fīnēs eōs īre paterentur.

     [The Helvetii] thought that they would either persuade the Allobroges — because [the Allobroges] did not yet seem to be well-disposed toward the Roman people — or would compel [the Allobroges] by force to allow [the Helvetii] to go through their territory.
     (The future active participles persuāsūrōs and coāctūrōs serve as complementary infinitives to the verb exīstimābant: “They thought … they would [be able to] persuade … they would [be able to] compel ….”)

First/second-declension adjective.
