 ==== Relative Timelocks with CHECKSEQUENCEVERIFY (CSV)
 
-((("scripting", "timelocks", "relative timeclocks with CHECKSEQUENCEVERIFY")))((("CHECKSEQUENCEVERIFY (CSV)")))Just like CLTV and +nLocktime+, there is a script opcode for relative timelocks that leverages the +nSequence+ value in scripts. That opcode is +CHECKSEQUENCEVERIFY+, commonly referred to as +CSV+ for short.
+((("scripting", "timelocks", "relative timelocks with CHECKSEQUENCEVERIFY")))((("CHECKSEQUENCEVERIFY (CSV)")))Just like CLTV and +nLocktime+, there is a script opcode for relative timelocks that leverages the +nSequence+ value in scripts. That opcode is +CHECKSEQUENCEVERIFY+, commonly referred to as +CSV+ for short.
 
 The +CSV+ opcode when evaluated in a UTXO's redeem script, allows spending only in a transaction whose input +nSequence+ value is greater than or equal to the +CSV+ parameter. Essentially, this restricts spending the UTXO until a certain number of blocks or seconds have elapsed relative to the time the UTXO was mined.
