When using expressions uncertainly the second clause (second half) of the statement is always in the verb tense?

When using expressions of uncertainty, the second clause of the statement typically uses the subjunctive mood or a conditional tense to reflect the uncertainty or hypothetical nature of the situation. For example, phrases like "If I were to..." or "I doubt that..." indicate that the second clause conveys a possibility rather than a certainty. This structure helps to clarify that the outcome is not guaranteed.
