Conditionals in Welsh grammar present various exercises that challenge language learners to articulate subtleties of hypothetical, potential, and actual situations. These exercises focus on the ‚taswn i‘, ‚petaswn i‘ and ‚tasai‘ structures, which roughly correspond to the English „if I were“, „if I would“ and „if it were“.

Through these exercises, students learn to construct sentences indicating possibilities, likelihoods, or uncertainties, reflecting everyday conversational Welsh. A good example of a Welsh conditional exercise might be translating complex sentences from English to Welsh, like, „If it were sunny, we would go to the beach“.

Often, these exercises also include identifying and correcting common mistakes when dealing with conditionals — an essential component to fluency. Emphasis is given to conjugating verbs correctly in accordance with tense and mood. The breadth and depth of such exercises help Welsh language learners to explore and better understand the grammar behind the unique conditional structures.
