6-letter words with I as the 1st letter and L as the 4th letter

Only 19 tournament-dictionary words put I in the first slot and L in the fourth, so this is a narrow pattern rather than a broad word family. Familiar examples include INFLUX, INFLOW, and ITALIC; less familiar entries include IMPLEX and ISOLEX. Just one match ranks among the top 25,000 English words by frequency, and 18 of the 19 have definitions.

The pattern at a glance

• All 19 matches begin with I and place L fourth.
• Seven end in S; three end in X.
• IMPLEX scores 17, the highest among these examples.
• INFLUX scores 16 points; INFLOW scores 12.
• Collins includes 19, compared with 12 in NWL2023 and 11 in ENABLE.

Which words are worth checking first?

IMPLEX leads at 17 points, with INFLUX one point behind. IXTLES and ISOLEX each score 13, while INFLOW and ICKLER score 12. These top-scoring choices share a useful feature: X adds scoring weight, so a rare-looking word can make a strong play when the board gives it room.

Not every match appears in every tournament list. Collins has all 19, but NWL2023 has 12 and ENABLE has 11, so check your game's lexicon before playing a less familiar entry. The frequency split is stark: only one match falls within the top 25,000 English words, despite recognizable examples such as INFLUX, INFLOW, and ITALIC.

How to narrow the I-first, L-fourth pattern

Start with the final letter when your crossing tiles are uncertain: seven matches end in S, more than any other ending. X is next with three; D appears twice, while C, G, M, N, and P each finish one word.

That split gives you a quick board check: an S at the end points to the largest group, while an X ending leaves only three candidates. The 19 6-letter words with I first and L fourth also include 18 defined entries, but their rarity makes an unfamiliar match worth checking against your game's dictionary.
