feasible
Possible and practical to do.
ExampleThe proposal is feasible because it uses existing campus resources.
ExampleThe professor questions whether the plan is technically feasible.
Usage Scenarios
Evaluating a proposal
Use feasible when the question is whether a plan can actually work.
ExampleThe plan is feasible because the university already has the necessary equipment.
Listening to objections
Listen for it when the professor doubts whether an idea is practical.
ExampleThe professor argues that the solution is not feasible in remote areas.
Usage Guide
Recognize feasible when a passage or lecture evaluates whether something can realistically be done. TOEFL academic tasks often judge plans, methods, and solutions.
Useful chunks include feasible solution, feasible plan, and feasible approach. Add because to explain the practical reason.
Do not use feasible when you only mean attractive or desirable. Feasible focuses on practical possibility.
Word Forms & Word Building
Feasible uses the adjective suffix -ible, which often means able to be done. A feasible plan is able to be carried out in practice.
Feasibility is the noun formed with -ity. It means practical possibility: the feasibility of the proposal.
Infeasible adds the negative prefix in-, but not feasible is more common and usually clearer for TOEFL learners.
Meaning Boundaries
Feasible vs possible
Possible means it can happen. Feasible means it is possible and practical.
Feasible vs effective
Effective means it works after implementation. Feasible means it can realistically be done with available time, money, technology, or support.
Register
Feasible is formal and useful in TOEFL writing, lectures, and problem-solution passages.
Memory Tricks
Think can be done. Feasible means possible in the real world, not just in theory.
Pair feasible with solution and plan because these are common TOEFL contexts.
When evaluating feasibility, mention time, cost, resources, or technology.
Common Traps
Do not use feasible for people. Use qualified or capable for people.
Do not confuse feasible with visible; the meaning is different.
A plan can be feasible but still not ideal; feasible is about practicality.
