Accepted Answer

[dɪ'fɪʃnt] 
deficientinadequate in amount or degree
Deficient means not enough or not adequate. Maybe you were deficient in caffeine that day. Maybe you were lacking in study time. But no doubt about it: you came up with a deficient amount of correct answers on the physics test.
If your new car fund remains deficient, you don't have enough money to buy a new car. This presents a problem if your current car is deficient in some way––say, it no longer has enough engine power to drive up a hill. You may not feel you have what it takes to get a job, but the reality is you will have to chose between indulging your own deficiencies in this area or the car's.
