Fill in the missing words in the second row using the letters M, O, T, L, E, N and the given partial words.

Let's analyze the missing words in the second row based on the grid structure and crossing letters. The third row is already completely filled with "LET", "TON", and "TONE".

Second Row, First Missing Word (4 letters):

• It starts with 'N' (from the word "EON" above it).
• Its third letter is 'E' (from the word "OMEN" to its right).
• So, the word structure is N _ E _.

Let's find a 4-letter word from the available letters (M, O, T, L, E, N) that fits N _ E _.
