天 (Heaven / Sky) vs. 夫 (Husband): The 1-Millimeter Top-Poke Kanji Difference
Both 天 (Heaven / Sky) and 夫 (Husband) are built by adding a second horizontal bar above 大 (Big Person). The entire difference is whether the person's head stops beneath the top line or pokes right through it!
Compare 牛 (Cow) vs. 午 (Noon) and 夫 (Husband) vs. 天 (Heaven): both pairs use the exact same visual principle — does the vertical center stroke poke through the top ceiling bar or stop flat underneath it?

5-Second Memory Summary: How to Never Mix Up 天 & 失 & 大 Again
Nothing can rise above 天 (Heaven / Sky — 天気 tenki), so its center line stops flat underneath the top bar! In ancient China and Japan, an adult married man wore a hairpin through his topknot, so the head pokes up through the top bar in 夫 (Husband — おっと otto)!
