I think he tries to say engulfing.
Dear Saurabh, Please learn to read the chart as it is, do not force a pattern, The previous candle is a nice hammer pattern rejecting the trend line drawn by you. That shows bullishness, and the following candle is a strong bullish candle with very little lower shadow and trading above hammer high justify the bullishness in the previous candle. But you need to wait for the close.
ALso do not forget to confirm your chart reading by checking higher timeframe market structure.
