We know that a suffix is often added to a word stem to create new words, but that isn’t always the case. Let’s take the example of the suffix –ducir in Spanish and some verbs formed with it: conducir, reducir, deducir, etc. Such verbs are derived from Latin ducere, which meant “to lead”. The examples below are cognates of English verbs ending in either “-duce” or “-duct” and their meanings coincide in English and Spanish. They have irregular conjugation in the first person singular in the present (yo conduzco) and its preterite forms are conjugated as conduje, condujiste, condujo, etc. The website 123 Teach Me (www.123teachme.com) has a very good Spanish verb conjugator, so make sure you check it out. Here are the most common verbs ending in -ducir, along with a usage example of each:
