"WEATHER" and "WHETHER"
"Weather" refers to the atmospheric conditions. "Whether" is used to introduce alternatives or choices. Ex.: The weather is perfect for a picnic. I'm not sure whether to wear a jacket or not.
"IMPLY" and "INFER"
"Imply" means to suggest indirectly. "Infer" means to deduce or conclude from evidence. Ex.: Her silence seemed to imply disapproval. From her reaction, we can infer that she is unhappy.
